As a die hard Merc fan, who's also a die hard Schumi fan, my head exploded in 2010 when everything fell into place. I'm not sure where to post this among the many threads, but since it's specifically about the 2012 team and not speculation I'll post it here.
I know most of the Schumi fans in here have always been Schumi fans but NOT Merc fans, so the pitch forks and torches were inevitable. I know it's upsetting, but this isn't 2006. It's come out in the news that Merc was forthright about this. They offered Schumacher a contract in July, and told him if they had to wait until October they'd need to start shopping around for drivers and Schumacher could lose his seat. Schumacher was fine with this, and knew of the Hamilton plan all along.

As for the rest of 2012, we've got 6 more races. Perhaps we'll still see Schumacher win this season. The car is only going to get faster for the rest of the season, now that their development program is back in full swing. With Mike Elliot on board, I think the team is finally locked in. With any luck, we should see some good races within the rest of this season.
As far as the "What was that?! What was that?!" incident goes... that tone could be either friendly ribbing or hugely disrespectful; it all depends on who was saying it. If it was Brawn, then I'll call it friendly ribbing.
Let's hope for some good races for the rest of the season. At least we've been given enough warning that we'll get to savor these last few races with our favorite driver.
