A Square Enix game designer from Osaka has updated their public 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. If true, the listing also confirms some Kingdom Hearts III info such as Pixar involvement, a possible Gummi Ship system, and possible multiplayer! 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:

This listing can be seen by searching for "kingdom hearts 2.9" on LinkedIn while logged in. While there is a small possibility that this page is fabricated, we have considered that their profile is linked to other profiles that we have verified as legitimate, and that their page contains a whole range of information about the game designer's career that is legitimate, and so we believe this to be true.

This news follows a leak from E3 2015 where Kingdom Hearts 2.9 temporarily appeared on the official Square Enix Presents schedule screen, before being quietly removed. This was also suspected to be fake at first, but we have since verified that Kingdom Hearts 2.9 did indeed appear on this official screen on the show floor. Was it a mistake, or something more?

If true, it is unknown exactly what Kingdom Hearts 2.9 could be. Is listing Kingdom Hearts III's Attraction Flow underneath Kingdom Hearts 2.9 a mistake, or could this new game be used to show off some of the Kingdom Hearts III gameplay features? Initial speculation was that Kingdom Hearts 2.9 could be a re-release of Kingdom Hearts HD 1.5 ReMIX and Kingdom Hearts HD 2.5 ReMIX, but comments by Nomura in an E3 2015 interview seem to indicate that there are no plans for this. Was the game cancelled, or will it be announced in the future? Only time will tell.
