the only thing ps2/ps3 has that xbox/xbox360 doesent is more games other than that, the xbox owns, it has internal memory, it now comes with wireless 802.11g access, well the ps3 does also but seeing as xbox is created by microsoft, im pretty damn sure it will be better, the xbox 360 comes WITH wireless controllers, and you can hook it up to your computer/laptop as an accessorie, im not gonna go into detail cuz i dont feel like it, as for the revolution the controller is gay as fuck it looks like a fucking dvd remote with an analog stick, and an add on where you can hold the anolog stick in your other hand WTF!!!!! plus the nintendo revolution looks gay itself, the thing i like about ps3 is their controller is gonna be usb, so i can use them for my computer games and emulators :-)
