So far it seems that they've tightened up camera controls and aiming on a PSP, looking at the ease the players are maneuvering and getting headshots.

BUT I do agree with you - there's really no reason to make a free camera game on a PSP. Furthermore, there really wasn't much need for a free camera in Metal Gear to begin with. Metal Gear Online needed it, but not the main MGS. Still, it did kinda evolve the series, and I'm glad its there, but a safer route that would've got me more excited initially would be to have that same fixed camera from optimum shots of original MGS.
