I would take a good guess and say it is Dragon Age: Inquisition

Inquisition is rated M, it has a lot of sex on it, is not dragon age.

Saying that it´s not as powerful as the PS4/X1 may be true but saying that it´s not at all is just ignorant. I highly doubt it´ll be KH3 but from a "could it be" point of view i´d say yes because it really doesn´t look as demanding as say GTA5, the order or whatever other realistic looking games there are. There are tons of current gen games with last gen ports so the real question is not if it´s possible but would someone bother with it/is it profitable enough?

Release this as a trilogy for WiiU including both KH1+2 HD and I'll buy it.

time will tell, speculate all you like, i hope for the best for wii u and for the fans, but keep your hype meter in check or it will bite you all if it's far from the reality.

Also it's made by EA, and EA doesn't make WiiU games anymore. They really hate the U, with all the discussions they had with Nintendo about the Origin thing.

From the article:
"Last year, we heard that Tantalus Media – the developer behind Mass Effect 3 and Deus Ex: Human Revolution’s Wii U versions – started work on a “AAA next-gen title” for Nintendo’s console. It was confirmed soon after that the project in question was a port/rework of a game “for an absolute top notch publisher.”
Although we haven’t heard anything about it for about a year, the title is fortunately still in the works. Tantalus’ Tom Crago said during the Fragments of Silicon podcast that it will be revealed “soon”, is launching this year, and is “the biggest thing we’ve ever done”.
Crago’s full comments are as follows:
We’re doing that. It hasn’t been announced, but it will be soon. And can I just further add to the mystique and say that it’s big. It’s the biggest thing we’ve ever done. And it’ll come out this year, and I hope it won’t disappoint."

Reasons to think that it isn't KH3:
They've been working on the port for a year already and I doubt KH3 was at any point to be ported a year ago.
The game they're working on is going to release this year and there's not a chance in hell KH3 releases in the West this year.
Far as I can tell these guys have never ever ported a Japanese developed game, and they especially haven't ported a Japanese developed game before it even released in Japan.

So yeah, KH3 may or may not end up coming to WiiU but I highly doubt that this announcement is for KH3.

Not likely, but maybe the Wii U can get the KH1.5 & 2.5 collection at best.

The Wii U GPU is about 20% as powerful as the XBOne. if the XBOne version runs at 1080p with light AA then its possible for the Wii U to possibly run it at 720p with no AA. If the XBOne is anything below 1080p then a Wii U version is pretty much impossible. If they do (they wont) make a Wii U version it would more than likely be lower than 720p....

This is much more likely
