Do the new MacBook Pro Core i7 overheat while running Windows?

I personally experienced insane overheating with older MacBook Pros when running Windows Vista or XP on them via bootcamp. Turns out this was because the video card would max out and poor bootcamp driver support (or something to that extent). My question is, do the new MacBook Pros with the i7 processors and the video card switching technology overheat? Additionally does anyone know if the switching technology would work while running windows and how is the battery life while running windows?
