I think the problem is that, unless a platform game has Mario in the title.. It's going to be a hard sale for any publisher. We saw terrible numbers for Rayman Legends (on all platforms) and also Sonic Lost World - Even though it's arguably one of the larger, sellable and more well known franchises out there.
Saying that, Donkey:Kong Tropical Freeze should do fine in NA. As for the rest of the world; EU, Asia and Japan its more than likely going to bomb.
