Besides the fact that they're all now "current" generation, I think I'll wait until they become "last" generation (when the SONY PS4, MICROSOFT XBOX 1080 Xtreme!, and NINTENDO YIPPEE! come out ). I'm always at least one generation behind the trend and snag lots of cheap games because of it

As for which to buy? Possibly the PS3 if it drops significantly in price (I don't even own a PS2 yet!) or the Wii (for all the older games).
