720p for Cutscenes, 480p for gameplay. Possible?

[Fernando]

I really think that technically, the Wii can output at 720p, at least the cutscenes and menus, etc. or some not complicated game, like some WiiWare titles (but the extra resolution would mean bigger size).

I mean, even the PS2 could output at 1080i (Gran Turismo 4) and the Xbox had some 720p games...
