GP2 2007, Who else could win?

This year in GP2 there has been differnt winners in EVERY race:-

Fillipi, Lappierre, Senna, Glock, Maldonado, Pantano, Villa, Zuber & Carroll.

Who else could win?

Lucas Di Grassi and, perhaps, Mike Conway.

Kazuki Nakajima should be in with a shot for a win, he's very fast and once he sorts out qualifying he won't have to fight past everyone every race. A couple of rough edges so far but he's got talent.

di Grassi's second in the championship but without a win isn't he? He has to be favourite, followed by Nakajima.
Are any F1 teams looking at Glock at all? I've not heard his name mentioned in line with anything, and if he can't make it I don't see who from this season would. I hope they don't fast-track Senna into a seat, he's good but probably not ready yet. Same goes for Nakajima too.

Zaugg (if the spelling is correct) does have a reputation for erraticism, doesn't he? He could be a bet to at least deliver a podium or two whenever a few other drivers find themselves 'off colour'. I know he isn't the most obvious choice but then, judging by the A1 GP record, he's hardly Pippa Mann...

I was expecting Zuber to be victorious a little earlier, hence the Pickems, so we'll have to see how consistently he can now perform.

Nakajima and di Grassi are the drivers who I think have chance in feature race. In sprint race many more names could be added if driver gets pole or 2nd on the grid.

We haven't seen wet race this year, that could change things as well.

I think kazuki Nakajima will win some races in this season :D
