I wish there wasn't so much rivalry between the ps3 and xbox as, at the end of the day, they both do the same thing. Myself, i prefer the PS3 mainly because im loyal to sony, but also because I think its aesthetically better :). I only bring this up as after watching videos from E3, i've seen that the new Splinter Cell Conviction game is exclusive to the xbox which has annoyed me as im a big fan of the Splinter Cell series. It didn't bother me at first when Metal Gear Solid 4 was brought out solely on the ps3 as I have a ps3, but now more and more games are being released exclusive to one platform or another and I think its unfair on gamers as we pay so much for the console in the first place, we're then not able to play any game we want unless we buy both consoles.
Hopefully, in time, game developers won't make games exclusive to one console.
