The only "official" piece we know is that Comcast\UC is partnering with Nintendo. We don't know where (officially, not something said by Sean, Joe, Hate, E.T.C) Nintendo will pop up.
Hell, I think even if we get Nintendo news for any of the three major Unis resorts (Excluding USS & USB); it'd be more in line as both a press event and having PR come in, like how USH had "Hogwarts is coming to Hollywood". Just, on a somewhat larger scale with Reggie and miyamoto announcing it either there, or by Prerecorded content.
It makes sense, and it allows Comcast to appease the park fans, and then the video game fans. But, I could just be a idiot, but hey; it is my two cents on stuff like PR possibilities and other things..
And yes, another example of me being bored.
