Heidfeld – when Kubica returns thats it for him i think, like others have said though he’d be a strong candidate for a seat at BMW in DTM – but as far as i know, they have already 2 confirmed race drivers – i read it on Autosport a few days ago. So assuming BMW will run 2 cars initially in DTM, not counting customer teams if there are any, that may not be possible.
Trulli – old news i’m afraid, Jarno is way past his use by date i think. If Chandhok does well in Germany this may be the end, depending wether you beleive Fernandes’ PR machine.
D’Ambrosio and/or Liuzzi – D’Ambrosio isnt spectacularly quick, tbh i forget he even exists in races and ive never seen him above the bottom 3 rows as far as i can remember. IMO there are more worthy, non pay-drivers who could fill his seat.
Liuzzi – as previously reported, could be replaced by yet another pay driver. Which is very sad as gaining an F1 drive shouldnt be about your bank balance and more about talent. But, thats how it is at the crappy end of the grid..
