Yes, they are. EA is not going to give the Wii U as much support as they will give the X1 and PS4 -- that is, if they ever give it any support at all.
The Wii U is most likely not getting Final Fantasy XV or Kingdom Hearts 3, so we can rule out Square-Enix as a source of even third-party support.
Konami? Pfffhahahahaha. No.
Support from Capcom, Activision, and Ubisoft is up in the air. I'd say a lot of that is riding on sales this Holiday.
Namco-Bandai is an odd case. They've been surprisingly buddy-buddy with Nintendo lately, and yet no SoulCalibur II for Wii U. We'll see how that plays out, though. Like Capcom, they have few upcoming games announced --basically some exclusives and remakes, and Dark Souls II, a game not being developed internally.
But really, the Wii U will get 50% of the third-party support the X1 and PS4 will get at best. It already has much more than the Wii got, though.
