Game Watch Impress is reporting that Zelda Musou/Hyrule Warriorsis still on track for a summer release on Wii U in Japan. KOEI-Tecmo’s CEO Erikawa has also mentioned in the same article that there will be another new large-scale collaboration coming in the latter half of the fiscal year. Sadly Erikawa wouldn’t give any hints as to what this new collaboration might be.

I want hyrule warriors earlier seems like a great filler for the big games.

Isn't this the new Fatal Frame that was announced a couple weeks ago?

Perhaps that Mario Warriors game is coming after all.

Is it a nintendo game?

I repeat this question. I can't find any quote saying it's for a Nintendo platform.

My work computer can't display Japanese text for some reason, but people at GAF are saying it's a collaboration on a western IP.

No this is something yet to be announced

Isn't it Fatal Frame? If not, then I'm game for another game.
