I believe DonWii means that the first Manhunt was made for the PS2, and Manhunt 2 is also being made for PSP and PS2. It probably isn't far from the truth to suspect that they built it with the PS2 in mind, then took the game, upped the res to 480p, added motion controls, and also upped the gore factor a notch to match the extra power in the Wii. It's getting released at the same time though, so it's technically not a port.
