I don't know. On one hand, the right kind marketing can sell any game. Not to mention that people sick of gimmicks may return. I'm not too sick of them, but I know there are people who are, so who knows?
On the other hand, there's always the issue of little to no marketing, and quite frankly, that may hurt its chances, gimmicks or not. It's a key factor here, and unfortunately, Nintendo doesn't seem keen on it, even if a game had something they could market with little to no trouble (like WarioWare: DIY. How many kids would like to make their own games, however small? Yet it had very little advertising. It's a gimmick, but I felt it was best to use it as an example.)
Even a game like this could get advertising out of heralding it as a "return to form" or something like that. I like the post-Touched games, but people who fell out afterward are out there, and they may need some incentive to think about coming back.
Just stating my thoughts is all.
