I was hoping that Irem's 95% finished Disaster Report/Raw Danger PS3 sequel would eventually see the light of day. I remember something about Grezzo (Irem's breakaway team) wanting to finish the project some day.
Maybe this is one of the Nintendo exclusive pickups that was hinted at.
That's what Monolith Kyoto and subcontractors like Bauhaus and Hexadrive are for. EAD hasn't made a Zelda completely internally since Spirit Tracks in 2009.
Noteworthy: the only two games they mention on that page are their two 3DS games.
