well it seems that technically, the Samus model in the FMV is both more detailed/complex, has higher resolution lighting as well as far better image quality with anti-aliasing , motion blurr. but these things could not be expected of Gamecube in a game (or even a realtime cutscene for that matter) .I'd expect Nintendo Revulution to pull this shit off with ease...
that of course says nothing about the artwork or environments. the enviroments in Prime and Prime 2 blow the FMV environment away. imo.
