" Backwards compatibility does not equal framerates at this level, removed jaggies, true 720p, or trophy support. People who are claiming conspiracy aren't thinking logically. No one is complaining that Microsoft has stopped supporting its backwards compatibility (though that's probably because no one wants that garbage). No one expects Nintendo to have an extra compartment in their consoles so you can stick your old NES, SNES, and N64 games in and play them at your whim. Etcetera. "
You're forgetting the part where the Wii has full GC BC (geez... that sound awful), the DS has full GBA BC, and every version of the Xbox360 has the same Xbox BC.
The PS3 had HW BC at one point, then removed it to cut costs and implemented a SW BC (granted it wasent has good, couldnt run as many games but still...), and then just removed it, only to start selling HD versions of their old games.
Edit: Also, I'm not expecting any company to support an old medium. Sticking a cartridge port on the GC/Wii would be retarded, not only due to the fact that on the Wii the port would be as big as the console.
