i had the same question like you about a week ago i've seriously waited about a year before i made a choice a have a ps3 now and i'm very happy with my purchase great games and the future looks very bright
and thats not really the case for the xbox 360 (imo)
but like all the others are saying it's you're choice and you should just check for the games you like but i had a better feeling with the playstation so goodluck !!
