Kingdom Hearts 2.9 in the Works at Square Enix?

It appears another Kingdom Hearts game may be in the works over at Square Enix, thanks to some revealing information on the LinkedIn page of a game designer from Osaka.

According to the Square Enix designer, he worked on a game called Kingdom Hearts 2.9 from August 2014 to June 2015. The platforms attached to the alleged title include both PlayStation 3 and PS4, leading one to think this may be a compilation of the prior HD collections that released not too long ago on Sony's last-gen system. It sure would be a great way for those who've already made the next-gen jump to revisit the earlier games before the release of Kingdom Hearts III
 

Speaking of Kingdom Hearts III, the listing also notes that the Gummi Ship will be featured in the game, as well as possible involvement with Pixar. We've heard rumblings of added multiplayer in the past, which also gets a mention here. 

Here's a full look at the designer's profile details, courtesy of KH13.com

What do you think Kingdom Hearts 2.9 might be? Do you think this whole thing is just an elaborate error, and nothing of the sort is actually in development? It is a rather ridiculous name, but don't forget, Square Enix is hardly a stranger to horrendous game titles.
