The issue isn't if this game will get published. It will. The issue is will it get published by a competent publisher.
Thus far third parties have been almost completely inept at marketing Wii games. Most third party games have no serious attempt at advertising and/or are ridiculously undershipped. And that's if the game doesn't suck in the first place.
My biggest worry at this point is if Ubisoft publishes it. Hey, they don't mind publishing upmarket games on the Wii, they just don't like making them. They know they can make an easy 100k in sales without having to spend a dime on advertising, but they can't be arsed to put any effort into making sure it sells beyond that.
That's why I hope Nintendo picks it up, like rumored. Yeah, it wont help things as far as the perception that only Nintendo published games sell, but it will at least have a real shot at being a million seller.
