You should wait until e3. It's this Monday June 10th. Personally I would say the Ps4 since the ps3 had a large variety of games to choose from besides 1st person shooters unless you like those then probably the X1. Depends what games you like.
Ps4. Instant downloading, paddles with touch pads on them, cooling grips on the paddles, every ps1 and ps2 game on the store, you can play online with ps3 users, the list goes on. Xbox one is just voice active...oooooo. Thing cool at all. Ps4 all the way
