It's just pointless to buy XBOX 360 and PS3, because you will miss great games like the Legend of Zelda, Mario, Super Smash bros, Paper Mario, etc. Besides, you won't be able to feel the great controller that Wii got.
It's such a stupid idea to buy PS3 and Nintendo Wii, because you will miss AMAZING games like Halo 3(Don't even need to explain) and ONLY FOR XBOX 360 titles.
It's just a perfect idea to buy XBOX 360 and Nintendo Wii, because you will eventually get to play all of the games you would like to play on the next gen consoles, except for FF13 and MGS(Well, I don't know, probably MGS could be on the XBOX 360, just like MGS 2 Substance was on the X-BOX.). But well, who cares about Final Fantasy now anyway? I don't. I just am still happy with the Final Fantasy 7, and still playing it.
Anyway, I'm sure the XBOX 360 and Nintendo Wii will rule. I just can't wait for the Legend of Zelda: Twilight Princess anyway...
