Kubica may huff and puff about the Renault takeover, but the fact is, he has NO other option, really... Sauber hiring Kobayashi pretty much closed that door for him, unless the Schumacher thing really doesn't happen. Otherwise it's presumably Heidfeld in that seat. So Kubica really has nowhere else to go...

I am "afraid" Tung may get the second Renault seat.... urgh!
