I see that Sauber, Lotus and Force India had a meeting to discuss the F1 agenda of the big teams. They are wanting a more equitable division of the F1 money pot otherwise, so they say, the smaller teams (them) will be forced out. There was even a rumour that they would not race in Austin in protest. That threat was, apparently, dropped due to the damage done to F1 in the States following the 2005 Indy fiasco.
I am not a betting man, but I would not put money on them being at Abu Dhabi.
