First off I just want to say I could be wrong, but am pretty sure am not (unfortunately enough because i would love a star fox game).
The first thing that comes to mind is that Shigeru Miyamoto said he wasn't going to create a star fox game if the sales of star fox 64 3D was bad, Star Fox 64 3D was released months AFTER Retro was already creating their new game. Miyamoto of all people should know what retro is making. (probably the biggest reason why they aren't creating the game)
Second, recently Miyamoto said he would love to create a Star Fox on the Wii U, if retro was making a star fox game then odds are he would have never said that.
The list when the wii u was hacked, showing codenames of games already released and games that are possibly in deveopment, Mario 3d (or Nsmbu), yarn yoshi, zombiU, flipnote studios and wii fit are their but no star fox, another game there called "Metroid" is there (which is what retro could be creating).
4. Retro studios hired a bunch of people from shooter games. no games that are related to on rail shooters.
Also its not a new IP since its something we have all wanted them to make, My guess is that they are creating another metroid game.
Its also a idea that after pikmin 3 is done, they might start on a starfox game.
someone, anyone please convince me am wrong because my hype for a new star fox game has all vanished :'(.
