@CCC:
If that's the case then it will necessarily have to be the most graphics-intense MM game to date, because nothing in the series so far has hypothetically been too much for the Wii.
Well it really depends. They'd have to work on a different variation for the Wii, similar to how Sega did for Sonic Unleashed. That's a lot of work. Not to mention, Nintendo's DLC service is a pain in the ass to deal with, according to other developers.
@Buuhan1:
I mean, the PSP ports of MML 1&2 didn't see release outside of Japan cause they sold so poorly there.
There's also how Capcom has yet to get MML 1&2/MoTB published onto PSN via PSOne Classics. I've heard numerous reasons behind this, including some bullshit mumbojumbo to do with the rights to the games code being lost?
Source codes can easily be lost. It's why a lot of classics don't get ported and sometimes have to be remade from the ground up. It's why we haven't seen, and never will see, a port of Panzer Dragoon Saga. A lot of games during the 32-bit era seemed to have gotten lost over time.
As for the PSP ports, I believe it also has to do with the fact that PSP games just don't sell too well outside of Japan to begin with, as mostly everyone's pirating their PSP games or just using the PSP for emulation purposes for other platforms.
