I've actually been enjoying a bit of 3rd party content on Wii U. Most recently Arkham Origins, AC:Black Flag, Watch Dogs and Deus Ex: Human Revolution. These were all great experiences, I especially enjoyed having maps on the game pad to follow rather than having to pause the game like you frequently have to do on every other console.
On a large scale I don't think gimp'ed versions are what is holding 3rd parties back from greatness on the platform. The 3rd parties in a way fulfill their own prophecies by releasing the game with minimal advertising and fanfare. Releasing the games later doesn't help either. Nintendo could do more to increase the attention these titles get as a sign of good faith. Rayman Legends got some push and sold just as well on Wii U as it did everywhere else.
run away!
