And I still think my projections are optimistic.
Kitase has expressed interest in releasing Birth by Sleep as one of the titles in Sony's new PSP-to-PS3 initiative. Other than that, I'd be surprised to see any big ports or remakes before Kingdom Hearts 3.
Square Enix has not even confirmed anything on the Birth by Sleep: Volume II front beyond the teaser in Birth by Sleep: Final Mix. They didn't say anything about KH3D at E3 either. I'd say we've got a while yet. Re:coded was already this calendar year's Kingdom Hearts title, and they've been very good about releasing one title per year (Coded in 2008, 358/2 Days in 2009, Birth by Sleep in 2010, and Re:coded in 2011). I'd expect Kingdom Hearts 3D in 2012, Birth by Sleep: Volume II in 2013. I'd be surprised if we got Kingdom Hearts 3 before 2015 at the absolute earliest.
