Really will be interesting to see if the Merc's still great off the start(might be that it was just schumi/Rosberg were awesome off the grid), or maybe Red Bull finally fixed that part of the car.
If it rains later, which there is a very good chance of, its really almost anyones races. The guys upfront are often at a disadvantage as they are less willing to take a big chance on the switch to inters/wets, while guys further back often take the gamble and it pays off. It could be several showers, with lots of tyre changes, so who the hell knows what will happen.
Apparently Perez had a puncture on that first super softs run, and so wasn't aware of how poor the track was on slicks so got another pair. I still don't quite buy it as from what I recall, he came in for his second set with around 4 mins to go, and Button was already on his way in. He had time to go around slow, get inters, and go out, might be a excuse for the teams insane decision to put another set of softs on.
