Haha yea, full body suits would be freakin sweet! I would definitely buy a system that I could put sensors all around me so I could jump and kick and punch by actually playing the game. I think the Wii is sort of next gen, since its technology is new, it is unique and therefore it is next gen. But on standard hardcore gaming, the 360 has the others down. However I'm hoping here in the next year the PS3 will rise up and break out with some great games. Still the PS3 is great and the graphics are stunning and the gameplay, but its online seems to not be too good and online play is a must for next gen consoles. The PS3 is a tremendous system now, but I think the reason it isn't as popular is the price tag. If it was as much as the 360, it would have a much better chance in the sales. But I don't have a favorite system since I've only really played the PSP. I'll be sure to get a PS3 probably by this summer though

EDIT: Oh yea! I completely forgot about the Wii. Well I've played it cuz I used to have one, but I sold it a few months ago. It was fun at first, but it got old. I have Super Mario Strikers which was REALLY hard after the first couple of tournaments!
Madden NFL 07 was ok. And I played Zelda The Twilight Princess which was a classic but definitely what I had in mind, Zelda should stay as a standard controller game. And Mortal Kombat Armageddon sucked for it. Like I said, it was fun at first, but it got old. A 360 or PS3 would be better imo. or PSP I guess.
