The FIA has published the official entry list for the 2012 Formula 1 world championship.
The list reveals McLaren drivers Lewis Hamilton and Jenson Button will swap numbers next year, with Button taking #3 after finishing ahead of his team-mate this season.
Several teams appear with no drivers confirmed yet, with Kimi Raikkonen's team-mate at Lotus yet to be confirmed.
Force India had no drivers confirmed on the list, despite Nico Hulkenberg and Paul di Resta expected to be announced in its line-up soon.
Williams, Toro Rosso and HRT also had no drivers on the list, the Spanish squad having confirmed Pedro de la Rosa for 2012 earlier this month.
HRT also did not have an engine supplier attached to its name, but the Spanish outfit told AUTOSPORT it would use Cosworth engines and that only a paperwork issue had caused them not to appear on the list.
