Eurogamer.net has a great preview of Medal of Honor: Vanguard up describing it’s gameplay and how it looks on the PS2 and Wii. Check the blurb below and the link for the full writeup:

If this is sounding disappointing because you were hoping for a more significant change to Medal of Honor, we can think of one solution: pick the Wii version up. As well as looking a little prettier and running a little smoother it boasts an all-new control scheme using the Remote and Nunchuk. Put simply, aiming involves pointing the remote, moving uses the analog stick on the Nunchuk while jumping, reloading, swapping between weapons, shooting and the all-new sprint ability use buttons. Throwing grenades has you bringing the remote back then casting it forward, and guiding your parachute involves gripping the remote and Nunchuk in front of you like the straps. Best of all, a quick flick of the Nunchuk to the left causes Frank Keegan to execute a sharp 180 degree spin to face whatever’s behind him, a move that’s absent from the PS2 version. Whether these controls will make us more efficient Nazi battlers remains to be seen, but there’s just no question they’ll make this tried and tested formula feel a little more fresh.
