It's really because the same reason the PSVita hasn't been getting alot of support for things it should be. Not enough people are buying, so not enough of a market for the publishers to deam worthy of their time and money. It doesn't help that the Wii U's unique features make it even harder to port.

Batman: Arkham Origins had a season pass, but the eventually decided refunding everyone who bought it was cheaper then porting Cold, Cold Heart for example.
