A Square Enix game designer from Osaka has updated their LinkedIn page with the projects that they worked on at Square Enix from August 2014 to June 2015, and curiously "Kingdom Hearts 2.9" is listed here as a title for both PlayStation 3 and PlayStation 4. For the 10 months that they reported working at Square Enix, they supposedly worked on both Kingdom Hearts 2.9 and Kingdom Hearts III, making the following contributions:

1.5, 2.5 and KH3D on PS4 in one package would be amazing.

And if this is real it also seems to confirm there is a Pixar world in KH3.
I'll take that with a ladle of sodium chloride. I'd expect it to be 2.5 ReMix + DDD at best -- there's no way it's economical to release both remaster collections in one collection like that.

I'd love it, though. The 60FPS dream...
So the development of 2.9 started around the same time as Kingdom Hearts 3? Assuming the developer whose profile leaked this info started working on them from the start.
Given PS3 is listed, possibly an internal build of KH3 using KH2's assets to try things out?

KH 2.9 is such a dumb name, which means it could be an actual product's name ...
You know what, I would believe that title. Comes out before 3, is the necessary collection to get you all caught up, so why not name it literally a .1 number before the next mainline game?
