The Australian Open could be a classic
A deliciously unpredictable start to the tennis year has been summed up by the current unseasonal weather here in Sydney - all cloud and thundercracks - mixed with record temperatures down the coast in Melbourne ahead of the Australian Open.
And on the courts of the east, in the first two weeks of the season, we've had a 15-year old Brit beating the world number 26, a Henin/Clijsters classic final to roll back the years, a title for a player facing suspension only days previously, and mutterings of a new tennis "World Cup" to keep the off-court motors chugging. Delicious indeed.
So where to start?
The omnipresent Nikolay Davydenko seems to be the man of the moment on the ATP Tour. This man, I have to hold my hands up and admit, is quite amazing.

His relentless pursuit of points, pounds and prizes is now backed up by a livelier brand of flat and furious hitting which, in Doha, claimed back-to-back wins over Roger Federer and Rafael Nadal to win the Qatar Open, the perfect follow up to his 2009 season-ending success at the ATP World Tour Finals in London.
Perhaps these recent scalps will give him the belief to take the next step and win a major (his win over Federer was his second in three months, after seven years of trying in vain against the Swiss) but he remains a long shot for the title due to the talent ahead of him.
Nadal, the defending Aussie Open champion, is ready to prove that his troubles at the end of 2009 are behind him. Some extra depth on his groundstrokes - particularly his return of serve - has been noticeable in the early weeks of 2010.
Federer will be looking to reclaim the title he last won in 2007, Juan Martin Del Potro is going for back-to-back majors (not out of the question by any means), and Andy Murray will put some extra bite behind his crosscourt forehand, if recent evidence is anything to go by, in his search for a debut Slam.
The women's event has an extra pinch of turmeric thanks to the return of Justine Henin on a wild-card. Just like compatriot Kim Clijsters at last year's US Open, Henin is perfectly capable of going all the way and winning the title.
She may have pulled out of the Sydney event with a leg injury, but she was on the practice courts as soon as she arrived in Melbourne, looking fit and determined.
Over two hours and 23 minutes, they played out a greatest-hits-collection of a match, complete with Henin comebacks from dead positions, before Clijsters edged it 8-6 in the deciding tie-break. Stunning stuff.
After a few mediocre years, with stuttering attempts from Safina, Ivanovic and Jankovic to rule the world, we have the two Williams sisters and the two Belgians set to contest the heavyweight matches. Just like old days.
That's not to write off the next generation. Far from it. I'm excited about seeing further progress in 2010 from the likes of Wozniacki, Azarenka, Lisicki, Oudin and the other 15 or 16-year-old we haven't even heard of yet.

And then there's Yanina Wickmayer - another of the names making headlines in the first few weeks of the season.
After breaking into the top 20 with her run to the semi-finals of the US Open, Wickmayer saw her season close with catastrophe; a third violation of the World Anti Doping Agency "whereabouts" rule and a one-year suspension.
A vigourous appeal was sent through the doors of various courts around Europe, including the European Court for Human Rights, and, in a landmark ruling, the ban was overturned to leave her free to compete.
As a last-minute entry on a wild-card, Wickmayer turned up in Auckland and promptly romped through the field without dropping a set. The trophy was lifted with more than a slight grin of defiance.
Her "whereabouts" for WADA officials after the final? Cloud nine.
Further down the international news agenda, several British players have put in impressive performances at the start of the season.
James Ward, playing his first competitive tennis since contracting glandular fever in September, successfully qualified for the ATP event in Chennai. Work with Greg Rusedski in London and Toni Colom, from the Nadal camp, in Spain looks like it may be paying off.
Also in India, the doubles pairing of Colin Fleming and Ken Skupski reached another semi-final to suggest their remarkable breakthrough 2009 season wasn't a fluke, while, over in Auckland, Dan Evans won through qualifying as did Elena Baltacha, who had also qualified the previous week in Hobart.
And watching Ross Hutchins at close quarters this week here in Sydney, partnering Aussie Jordan Kerr to some fine results at the Medibank International, emphasised the battle for places in the Britain Davis Cup team this March, in the predictable absence of Andy Murray. Hutchins looked in fine nick.
The week began with Robson looking completely out of her depth, but, after a crash course in dealing with the big time, talent shone through with victory over the world number 26, Maria Jose Martinez Sanchez. It was Britain's single point in the 2-1 defeat in the final.
The Spaniard may have four names but Robson is the one to remember. Quietly, patiently, another star is emerging from these shores.
Back in Sydney, there was plenty of chat in the lobby of the official players hotel about the suggestion for a biennial, 10-day tennis "World Cup".
The plan, drawn up by a marketing firm and backed by leading players, would see countries competing at one venue in a succinctly packaged team format.
The idea, while nothing particularly new (Andre Agassi was saying this sort of stuff more than 10 years ago), makes total sense.
But tennis is all talk sometimes - that's all it can be when so many diverse interested parties run the sport - and this utopian vision needs more than blue sky thinking from marketeers to succeed.
It needs to be properly thought out, with a solution to every potential hurdle, and most importantly unity across the whole sport, with all its stakeholders (to borrow that horrendous corporate phrase), to avoid forever being seen as an unofficial, or "rebel", event.
The Davis Cup has its merits, but the format is overly complicated and increasingly irrelevant. The players no longer see it as the best format for international team tennis.
So will anyone listen to them?
An excursion out of "the tennis bubble" and into the real world should be obligatory for tennis officials, and I applaud the alternative idea and wish it every success, without holding out too much hope.
