Personally feel like Lewis has completely sold out. BBC suggested it was off the back of Brawn convincing him that they'd have a decent car come 2014, and relive the previous form he's had (Brawn). Personally however, I don't feel he can achieve it without a brilliant technical director like Newey.
I guess there's hope for Lewis that Alonso is doing so well in the Ferrari this year, but definitely feel Lewis will have to mature slightly by then. He has the ability to drive a car beyond it's limits, but I'm not sure how well he'll do it. But it's not like the Mercedes has shown any more reliability than the McLaren this season...
Perez moving to McLaren is a nice move, although personally would have preferred perhaps someone else feeling the seat (Di Resta).
The final question I guess would be Schumi. Peter Sauber saying he'd give him a seat is promising that people still value him, but, whether he'd take that kind of cut would be questionable. Personally, I'd love to see him go take Hulkenberg's spot at FI. They're doing alright at the moment, and the FI Mercedes link would support the move. I'd also quite like to see Schumi in Grosjean's seat, but not sure how realistic that would be as they already have Kimi as the 'older, wiser' driver... That said to be fair, even if he does only have Sauber's seat offered, Sauber are coming up the rankings well this year as well. Kobayashi and Perez have both done well, showing good form from the team...
