I've got Windows 7 32bit running on Bootcamp, just upgraded to Mountain Lion after being on Lion on an early 2012 MBP. I've found out Bootcamp 4.0 only supports Windows 7 64bit. The biggest problem I had with Bootcamp and Windows before is that the Nvidia cards were never recognized by Windows so my gaming experience (which I primarily installed Windows for) didn't always work. Right now I've downloaded Tomb Raider 2013 for Windows, which doesn't work because of the Nvidia problem in Windows 32bit - I can't update the drivers since Windows won't admit I have such a graphics card in the first place. I've got Windows 7 64bit in my Amazon shopping cart and have put the latest drivers on CD via Bootcamp, but before I purchase the $90 OS I want to ask - does this latest version of Bootcamp solve the nvidia issues? I don't want to spend the money if it makes no difference.
