a) I don't care about whether or not Nintendo will make money off this. They release so much trash that makes them tons of money, so I don't see how that's relevant.
b) You could take any game ever released and find people who haven't played it? They could port over New Super Mario Bros. Wii, which sold fifty billion copies, and there'd still people who never played it! Your argument was, "well, lots of people didn't own a Wii, so this is their chance to play it". Sure, fine, a lot of people didn't own a Wii. And a lot of people did. And if we're only counting people who didn't own a Wii but do own a 3DS, the group is even smaller.
And maybe those people should have considered getting a Wii if they wanted to play this so badly.
