Since New Play Control! Metroid Prime 2: Dark Echoes comes out in Japan soon we have screenshots for 1/3 of Metroid Prime Trilogy, the Metroid Prime 2 part of course.
No huge differences to note since this is based on a Gamecube game. The only difference I see is there appears to be a minor change in multiplayer mode. It looks like players have less vertical shooting room in widescreen mode.
