I've just been playing the (online MP) public beta, and am pretty impressed so far. This is actually a portable Killzone, and it looks and plays really well. Right now I've just been using the analog sticks, and that works great so far. I played two warzone matches, until at the end of the last one my (already low) battery ran out. Only downside I can see so far really is that the player-count is low, which feels a little weird in an online Killzone game, but the maps have been well-designed for it and so far the fights have been pretty good ... match-making was fast and effortless for me as well, with no connection drops or anything. Hope the single player campaign is good too, then finally the Vita seems to have a must have FPS!
