As reckless he has been, I thought he would have kept his seat, he was doing really well at the start, has gone off the boil after Hungary, or maybe his team-mate has just grown in confidence after having half season to get up to scratch?
I don't know if he deserves another season or not, he's had the pace, but he has been reckless, he isn't consistent either. He could pay dividends next season, but he might not either.
Out of all the candidates listed, I can't really see any of them replacing Grosjean. Maybe d'Ambrosio as he's the third driver, plus is under the same management as Grosjean.
RasputinLives you also forgot Davide Valsecchi who has done tests for Lotus and has impressed them, plus he's a GP2 champion.
I personally would like to see Valsecchi or Kobayashi beside Raikkonen, I am still unconvinced about Kovalainen.
