First of, right now I think Activision is the best Wii U third party support.
Now don't get me wrong, they're not perfect, Call Of Duty games being confirmed as late as possible, no DLCs; besides, why no DLC ? Is it only because the userbase is lower than on other platform, or is it because the 32GB of the Wii U meaning people most likely have to buy a HDD and then the DLC ?
Anyway, so far Activision is supporting the Wii U more than the other, even the Wii and its huge graphical differences with 360/PS3, Activision got a lot of Call of Duty games released on it, I know it's been only two for the Wii U and like always it's unclear if the next one will come up, but with Amiibos and SkylandersActivision isn't letting the console down, Nintendo gave kudos to Activision and Disney for using the NFC and selling them well(while Ninty refused Activision's approach http://www.egmnow.com/articles/news/nintendo-passed-up-the-opportunity-to-partner-up-with-activision-on-skylanders/ )
EA's not supporting the Wii U(well they didn't try much), Ubisoft is giving up, THQ died, Hotline Miami devs trolling (
@mathieuwarnier Hotline Miami 2 is coming to the N64, get hyped.

What does this all do ? This forces Nintendo to be more creative and not rely on their success, people got tired of New Super Mario Bros, we got way too much of them. They find out Miyamoto's ideas alone won't help, he can't make it without third party covering it all up, leaving free space for talented dev to show up and bring something that is creative AND a new IP, hello Splatoon.
Nintendo tries to bring some third party again, last time it was Bayo, now they get Devil's Third.
Really, all this is pushing Nintendo to make better use of their studios, because they sure have enough to make awesome games, but their commercial success with the Wii made them grow overconfident and wrong.
Last year I thought Nintendo didn't get what was E3's audience, but this year they got it all right.
The lack of third party might havedamaged sales so far, but it's only for the best, Nintendo is waking up to regain third party support, and they have a chance to succeed.
