There isnt room in the market for another high end gadget for people to carry around with them these days. People have tablets, phones, e-readers, portable consoles, laptops, MP3 players ...
The Vita is a fantastic gadget, but there just isnt a big enough market for such a focused high end product.
The only thing Crysis 2 was missing was the physics and destruction, interaction with the world is much poorer in Crysis 2. But everything else was great, better guns, better nanosuit, more interesting gunfights, more varied graphics and environments, better performance. I Think Crysis and Crysis 2 are EQUALLY good games, they both have their merits. Its mostly the PC die hards moaning.
