From Mistwalker, I want them to revive Cry On for Wii U and as said to make Blue Dragon for 3DS.
Whoever is left of Cavia at MAQL can do Cry On, and The Last Story team can get on Blue Dragon, hell if MS is fine with it, just go a head with a remake or a sequel to the original (a real Blue Dragon 2 that is similar to the original, the DS games changed things up).
Mistwalker and MAQL can do great things together, as shown with The Last Story, but perhaps their output can be a bit higher.
I'm also excited to see what perhaps Matsumoto and MAQL can create without Mistwalker, since it's Matsumoto who was always vocal about Wii U RPGs, why doesn't he just come up with something on his own?
Though all of Marvelous' Wii RPG aside were from outside devs (Rune Factory Frontier = Neverland, Arc Rise Fantasia = imagepoch, Valhalla Knights: Eldar Saga = K2) and same for 3DS (Rune Factory 4 = Neverland, Dragon Marked for Death(?) = Inti Creates).
Surely Matsumoto and the folks behind TLS at MAQL in-house can do one themselves.
