the Wii will be great, ps3 stole some motion sensing from them tho

.
There are attachments for the Wii controllers, one is exactly like the gamecube controller, you stick the wii in it.. Another is a joystick that attaches to the bottom of the wii and has a cord you hold it in your other hand.
I love the Wii (or wee hehe) I think it will be a great consol with a great controller.. I guess just people who want "uber leet graphics" and are too fat and lazy to get off their couch will go for the ps3/xbox360
Think of this:
You have the wii, 2 controllers, a friend over and a sword fight game.. You's could jump around in your living room slashing eachother, seriously how awsome would that be?
