Frankly, couldn't care less where he (or any other driver to be honest) drives. F1 is a business whose product is a sport.
That Hamilton has associated with McLaren for umpteen years is unusual, but eventually children do leave home, and this is pretty much what is happening here I guess.
I think that Perez could be very good for McLaren - he clearly has talent. I doubt that the Alonso situation will be repeated as FA was already a champion when he joined the team and was expecting to be alongside a compliant rookie. SP knows that Button is there, so no surprises.
Two things will be interesting from all of this - (1) how long before LH makes an impact at Mercedes, and (2) how far will McLaren design their 2013-15 cars around JB.
As for Schumacher, is this his second retirement? Guess that will be made clear later. There was a report that Peter Sauber would sign him if one of their drivers left and he became available....
Presumably all this secures Massa's position at Ferrari.........unless MSC goes there.....?????
