To answer my own question that I couldn't stop myself from asking even in my own thread: I think we get Mario Kart World at launch, a new 3D Mario in the first six months (not Odyssey 2 — a new concept), and Metroid Prime 4 within the launch year. Donkey Kong is the wildcard — it could be launch or it could be the holiday title.
What I desperately want and will almost certainly not get: a new F-Zero. It has been 20 years. Nintendo please.
