It's not really aimed to be a system seller. It will just be a game that helps fill out the fall library and sells 1 mill or so worldwide I think.
Which is about 10x more than a regular Dynasty Warriors game would sell.
So Nintendo gets an extra notable game to fill in a release gap this year and Koei gets a way to sell the musou series on the Wii U. Win-win ... what's the problem?
If Mario Kart doesn't sell the system, then Smash or anything else are pretty much pointless anyway. Zelda (from EAD or otherwise) isn't doing anything if Mario/Mario Kart falter.
