...Thinking about it, with the rumors that have floated around of USJ getting Nintendoland revealed and with NX revealing possibly in September; they could market it as a Nintendo Direct that goes to how the future of the company can work, with giving incite to it's NX offerings, Theme Park offerings, and the really unknown film offerings that they may be planning. It gives everyone what Nintendo has going forward and packs a big punch, especially if it's days before Tokyo Game Show; allowing them to be giving a much bigger punch in the future of the company than people could expect.
I'm expecting just NX, but I wouldn't be shocked if we get the Theme parks mentioned within the next few months or close to after the NX reveal itself to keep that Nintendo hype train going.
