How about neither? WoW FTW.
No red Wii at release = no buy.
PS3 is $600+ = no buy.
No games for the 360 that I am interested in = no buy.
I will wait for truly next gen content, and not this gen content with shiney graphics. Also, I just blew a lot of money one a MacBook, so I have to recoup before an HD tv purchase.
Remember gamers, just because the systems come out, doesn't mean we have to buy them. I will wait till I see a game I will play.
