Maybe Mikka should make a comeback as well. While I understand Schumacher's loyalty to Ferrari, I think this is a huge mistake. He is 3 years removed from sport, the car has completely changed, and I don't think he can get in it until first day of practise in Valencia.
edit: confirmed.. there is a driver testing ban. Drivers are not allowed to test drive the current generation of F1 chassis. Ferrari has sent a request to the other F1 teams and FIA requesting permission to get Schumacher into the F60 for a single day before Valencia. I say they grant the request, but allow every team the same opportunity.

Of course, there is always the change that he is that good, and will jump right in and start winning again.
It will be good to see him drive along side of all the young stars though. I for one am kind of excited for Valencia now. It will be interesting if nothing else.
