Actually, it has been confirmed that Retro is not the studio working on the game. Kensuke Tanabe is still heading the project, but Nintendo stated at a press roundtable that it had a new development team working on the project, rather than Retro Studios.
Which, interestingly enough, means that Retro still has a project that they've been confirmed to be working on for about three years that we have no other knowledge of.
I heard something different, that they working on the game. I will find this article about that. I came across this article ages ago.
