PS4 more powerful hardware which results in better looking multiplats, Soon Gaikai which means you can play PS1,2 & 3 games. Xbox better controller, better online service/Azure servers and better multimedia functions Both have amazing games and both have different exclusives. You cannot lose whichever one you go for. I went with Xbox first as it has the better games out...Will pick a PS4 up when Uncharted 4 hits or unless anything else comes out before that's a must buy.
