If it’s not officially Nintendo day at E3 2012, it might as well be. After the company’s Press Conference this morning, the Wii U is practically all anyone can talk about — and there is a lot to talk about. The system’s tech specs have finally been made (kinda) public, and fans and haters alike have finally had a chance to see what real, live Wii U games look like.

Predictably, new installments of beloved Nintendo franchises — in this case, New Super Mario Bros. U and Pikmin 3 — are getting the most attention, but that’s not the end of the story. Wii U has an impressively broad lineup of games, and we’ve got a group of trailers to show them off in style! Feast your eyes on the debut trailers for ZombiUScribblenauts Unlimited, LEGO City: Undercover and Project P-100.

ZombiU began life as Killer Freaks From Outer Space, an alleged Wii U launch title announced at E3 2011. A lot can change in a year — space is out, and zombies are all the way in. Developed by Ubisoft Montpellier, ZombiU could be some real competition for Aliens: Colonial Marines, at least where fans of M-rated games are concerned. The crowd at Nintendo’s Press Conference seemed to love this — could we be looking at the next Resident Evil? Check out ZombiU below.

Some ideas just make sense, and playing Scribblenauts on the Wii U GamePad is one of them. Apparently, the developers at 5th Cell think so too, and now there’s Scribblenauts Unlimited to prove the merits of the notion. It’s certainly the nicest-looking iteration of Scribblenauts yet, and multiplayer is sure to open up the experience in a whole new way — plus, for the first time, players will be able to create wholly original objects. Get out those thesauruses, and get ready for the Scribblenauts Unlimited trailer below.

LEGO City: Undercover is a LEGO game of a different stripe. Unlike LEGO: Lord of the Rings and LEGO Batman 2: DC Super Heroes, Undercover isn’t based on any other property — it’s all original LEGO. As undercover detective Chase McCain — which strikes me as a fantastic name for a LEGO hero — players hit the streets of LEGO City to take down villain Rex Fury. Simply put, this looks like a LEGO version of Grand Theft Auto, and it’s exclusive to Wii U — though a handheld version is in development for 3DS. Frankly, I think the portable game will have trouble stacking up, and after you check out the LEGO City: Undercover trailer below, you might just agree.

Hideki Kamiya is the director of Bayonetta. His company, Platinum Games, is hard at work on both  the chop-tastic Metal Gear Rising: Revengeance and the smash-tacular Anarchy Reigns (in which the lovely Bayonetta appears). Do you sense any themes developing here? Blood? Violence? Sex? Well, prepare yourselves,  because the next Kamiya-directed, Platinum-developed title is… a Nintendo-published, kid-friendly, Pikmin-esqe game called (for now) Project P-100. Oh, there’s still some combat, but Mad World (yep, another Platinum game) this is not. It may not have gotten the spotlight at Nintendo’s Press Conference, but Project P-100 just might end up as one of the most original games in the Wii U’s launch library. Check out the trailer below.

Ranters, what do you think of this batch of Wii U titles? Are any of these day one purchases for you? Let us know in the comments below.

Project P-100 will launch alongside the Wii U this Fall.

ZombiU, Scribblenauts Unlimited and LEGO City: Undercover are all due by the end of 2012 for the Wii U.
