Capcom just shot themselves in the foot.
I don't know how much the rest of you know about Japanese culture (I'm an expert), but honor and shame are huge parts of it. It's not like it is in America where you can become successful by being an asshole. If you screw someone over in Japan, you bring shame to yourself, and the only way to get rid of that shame is repentance.
What this means is the japanese public, after hearing about this, is not going to want to purchase MML3 for any system, nor will they purchase any of Capcom's games. This is HUGE. You can laugh all you want, but Capcom has alienated an entire market with this move.
Capcom, publicly apologize and cancel MML3 for 3DS or you can kiss your business goodbye.
This is the second most retarded statement have read on this thread (the first being ZeronHitaro's piracy comment, but that's already been pointed out).
It's a good thing we have self-proclaimed 'experts' here to pigeonhole the Japanese people into ridiculous stereotypes for us. Obviously by this logic Final Fantasy VII must have been a huge failure since nobody would buy it after Square 'screwed over' their fans by not putting it on a Nintendo system. I won't bother to check the sales numbers on that because who needs facts when you have absurd stereotypes? I'm sure somebody at Square had to commit seppuku to make up for it.
Also, nobody is being screwed here. It's ridiculous to think that putting a sequel on a different system is even an issue when the game it was a sequel to is already two generations out of date.
