In my opionion, the Playstation 3 will get number 1. Maybe not at the moment, but when big releases like WarHawk, Lair, Heavenly Sword, MGS4, FFXIII, LittleBigPlanet, GTA4(although multiplat), Killzone 2, Ratchet & Clank Future, Wipeout HD, Uncharted, Folklore, Tekken 6 and Playstation Home are released they will rake in the winning.
The only thing they need to do to secure their place is to fix things up like adding things to the Cross Media Bar and liven up the PsStore, which they seem to be doing at the moment.
To me, the 360 is old news, nothing brilliant coming out apart from BioShock and Halo 3, GTA4 will be out on the 360 but i'd rather the PS3 version. And paying for Live just made me angry.
The Wii, is a big, BIG bore. What good games? Zelda, SmashBros. Brawl, Metroid Prime, Mario Kart, and Mario Galaxy. After those are released, what the fuck do we look for after those? Just more sequels of those exact games, probably. I have more games on my Virtual Console than I do Wii games.
PS3 may not be winning now, but give it a year or so and come back, we'll see who's doing best.
