Could F1 2011 be even better?
The final grand prix of the season in Abu Dhabi summed up why the 2010 season will go down in Formula 1 history as a classic year.
Before the race was run, the sun-soaked paddock was buzzing with talk of "the greatest season ever" and debate about the highlight of the season swelled.
In fact, as the dust settles on Abu Dhabi, the teams' attentions are already turning to 2011 - all the teams and most of the race drivers get their first run on next year's new Pirelli tyres at the Yas Marina track at the weekend.
With just 118 days to go until the cars and drivers return to the desert in Bahrain to rejoin battle, expectations are already building that 2011 could be another classic year, matching events this season.
As BBC pundit Eddie Jordan exclaimed on Sunday: "We have five world champions competing next year, what are we in for?!"
Jordan is right to be excited.
All of them know they have things to improve in 2010 - particularly the number of errors they have made. And the long winter will give each of the 24 drivers on the grid time to analyse and agonise over crucial mistakes and frittered points that ultimately defined their seasons.
"Every one of us made too many errors and that is why we found ourselves in a position with five guys fighting it out," reflected Button, who saw his title defence end in Brazil.
Though he was the first to bow out, Button had the cleanest season of all the five contenders but found himself let down by a lack of pace - particularly in qualifying - as he got to grips with a McLaren in his first season with the team.
Alonso will rue his uncharacteristic errors in Australia and China, his crash in Monaco and, most of all, the fatal call from Ferrari to bring him in early for fresh tyres in Abu Dhabi.
Hamilton will reflect on his ill-judged passing moves in Monza and Singapore, which effectively ended his hopes, while Webber will relive his frightening somersault in Valencia and his costly crash in Korea.
Vettel, too, made more than his fair share of errors. He must take the blame for crashes with his team-mate Webber in Turkey and an unwitting Button in Spa, while his attempt to go around the outside of Webber at the start in Silverstone earned him a puncture.
When Red Bull adviser Dr Helmut Marko was asked on Sunday what his next goal was after his team captured both championships, he said they intended to cut out the errors so they could win the titles sooner.
All the top teams will be adding grease to their usually slick operations over the winter at the same time as building their cars to a set of regulations that have been tweaked again.
Blown diffusers - 2010's other defining technical tweak - will stay to an extent, though.
In come those Pirelli tyres, while Kers energy storage and power-boost systems return after a year away. There will also be a new technical trick in the form of moveable rear wings, an attempt to solve F1's perennial problem even in a season as great as this - the difficulty of overtaking.
The success of the teams' research into the effects of these changes will shape next year's title chase - and it is by no means a given that this year's big three will be the ones who get it most right.
There have been concerned whispers that the efforts of waging a season-long campaign have diverted attention away from 2011 development programmes at Red Bull, Ferrari and McLaren.
The strain of winning the 2009 championships certainly drained Brawn Grand Prix, which had a debilitating effect on them this season in their new guise as Mercedes.
However, with no championship to fight for, teams such as Mercedes and Renault, who stopped developing their 2010 car in September so they concentrate on next season, could make it a five-way battle for honours next year.
"It has been a special year," mused McLaren boss Martin Whitmarsh. "Can there be more?
"We have to keep the focus on brave, fantastic drivers in great machinery; an even-handed regulator, stability and clear rules that are administered properly.
"We can't guarantee it but there is no reason the championship next year can't be as good - or even better."
