As far as "AAA third-party" goes? Yeah, it's pretty much dead. You may see a couple more "mature" games for the system, but that's really not what the console is about anymore. Nintendo promised super amazing 3rd party support for the system back when it was announced, but the main "AAA" developers gave up on Wii U because, well, who knows? Because the Wii U is "underpowered"? Nah, more like they're too lazy to put any work into their ports. Because the install base isn't big enough? Huh, they must not be very confident in their game if they don't think it'll sell anything console-wise. And then there's Ubisoft. The botch and delay games for the Wii U then blame fans for not buying their games. When Ubi pulled Rayman Legends right out from under my nose, my decision was made, they were not getting any of my money. But, to be fair, I'm really not a big "AAA" guy. Don't care for "mature", gritty titles that think they're so much better than "kiddy" Nintendo games. However, this ordeal has lead Nintendo to pump out some amazing games for the system, and I wouldn't want it any other way. (A few more sales would be nice, though...)
TL;DR: If all you care about is third-party, then yes, the Wii U is very dead. But if you care about Nintendo's games coming out soon and in the distant future, then no. The Wii U is very much alive, more alive than it ever was.
*whew*, that felt good...
