Kingdom Hearts 2.5 developers have not made any announcements related to a Playstation 4 version of the title, but have mentioned there will be a collection of three games for the PS3, leaving many gamers wondering if the next-generation version's development will be cancelled.

Developers at Square Enix are expected to release a Kingdom Hearts 2.5 HD Remix trailer at the PAX Prime conference in Seattle in September, bringing some gamers to believe that they may also disclose a release date.

Square Enix has yet to announce an official release date for the successor game to Kingdom Hearts 1.5 HD Remix-it is expected to be one of the PlayStation 4's (PS4) most popular games, when developers finish next-generation production.

Gamers have already posted videos on YouTube of leaked content incorporated in the upcoming game.

According to Kotaku, the trailer includes limited edition remixed versions of Kingdom Hearts 2 and Birth by Sleep.

Square Enix is expected to release more 2.5 HD Remix release date footage at the PAX Prime conference.
