I voted Undecided. My friend has a 360, and it seems awesome except there's a limited (by limited I mean maybe 3) games that are on the 360 that I like that aren't on the original Xbox (which I have, along with PS2).
I'm thinking of either getting a Wii because 1: It's a steal compared to the mighty PS3, 2: The controller seems really interesting and some of the games look like they could have major potential, and 3: I have never had a Nintendo console, and they seem really fun.
I'm considering the PS3 because 1: I have PS1 and PS2, and I never even considered getting an N64 or a Dreamcast because Sony has made some incredible games when I was 5-10 and liked all the Crash Bandicoot, Spyro, Madden, Gran Turismo 1, Championship Motocross, etc, but when the PS2 hit the block, it was day and night. GT3 was my first PS2 game, and I was HOOKED. 2: The PS3 will have GT5. 3: I know that Sony systems are the longest lasting and selling (I only got 2 PS2's because one of them got suffocated when my house was remodeled by sawdust, dirt, dust, particles, chemicals, etc and died. The PS3 seems well worth the $600 I will have to shovel out from who knows where to get it, and it better damn last me 'till 2012, at least.
