3DS and Vita offer something that smartphones and tables don't offer, BUTTONS! I've had my ipod 4g since they came out but damn most games play like crap unless it's simple like infinity blade, angry birds, cut the rope, ect. Would you rather play a FPS or TPS on a smartphone or the Vita? Uncharted played so nice on the Vita.
There isn't any reason for them to show up. They don't publish that many games anymore and they have no new hardware to show off. Most Xbox 360 games are third party.
As long as it's not "run to point A, fight off hoards of enemies, run to point B, fight off hoards of enemies, rinse and repeat for 8 hours. Campaign ends. Time to play the same multiplayer in the last FPS you played"
