During a recent interview with longtime Kingdom Hearts developer and Kingdom Hearts 3 co-director Tai Yasue, it was revealed that Square Enix hasn't ruled out the idea of a PS4 compilation for its previous games.

Kingdom Hearts 1.5 HD Remix--which includes Kingdom Hearts 1, Chain of Memories and 358/2 Days--was released for PS3 in 2013, the same year the PS4 launched. Kingdom Hearts 2.5 HD Remix--which includes Kingdom Hearts II, Re: Coded and Birth by Sleep--was released for PS3 the following year. With the PS4 now the dominant PlayStation console, developer Square Enix still hasn't given a hard no on PS4 versions of both collections.

"We haven't come to decision and nothing is announced yet," Yasue said. "We listen to our fans and our players and see what they think about it--and, yeah, I'm not ruling it out, but we're not making an announcement just yet."

He then added briefly that development on Kingdom Hearts 3 was in full swinging, noting that it's "moving along fine."
