While I can understand, that EB, as everyone else, has limited resources, I think that the issue worth at least looking into for two reasons:
1.) The differences between W7 and Vista are minimal. Not like we ask to give PB support on Win 3.1...
2.) Most PB enabled games work fine on W7, indicating, that a.) it can be done b.) not much change needed.
So all I want is a normal reaction from EB like: "Dude one of our programmers checked it out, and he thinks it would take couple of weeks so we better skip this one." And not this: "We wont support beta OS. Not if the sky falls down. Period." Sounds like they don't even care :(
But I don't want to disrespect, or offend anybody, I'm just saying... :)
