I'm talking the full-fledged console RPG Thousand Year Door follow-up that many have been fanatically craving for over a decade now. One day Intelligent Systems...one day...
However, I don't think today is that day, because I totally forgot about:
Next Level Games. They have been known to be working on a Wii U title of an established Nintendo franchise since well before E3. I completely forgot about this since the hubbub of their Federation Force announcement. In fact, my bold E3 prediction was that NLG were going to announce F-Zero Wii U, and for the hell of it I'll stick with my initial prediction. Nintendo sees F-Zero as a very small/dead franchise which fits the hints so far (though so does Luigi's Mansion, Punch Out, and a host of other franchises). Plus everything that Doctre just contributed.
If I were a betting man, I'd say we'll finally find out what Next Level has been working on on Monday.
Also,
But I thought that game came to be Mario & Luigi Paper Jam?
Not likely. The pamphlets said the Paper Mario game in development
was a Wii U title. Your guess is as good as mine if it has been moved to NX or not since.
