Tetsuya Nomura told Famitsu magazine. As Gematsu reports, following last month's announcement of 1.5 HD Remix, Nomura admitted a second HD update for the Kingdom Hearts series is probably going to happen.
With Kingdom Hearts, Chain of Memories, and 358/2 Days being bundled in 1.5 HD Remix, we'd wager our limited edition Goofy figurine on a second update including the remaining major releases, namely Kingdom Hearts II, the PSP's Birth by Sleep, and the recent 3DS game 3D: Dream Drop Distance.
Nomura also dished a few more details on 1.5 HD Remix. Rather than upscaling old character models, the update will simply feature those used in Dream Drop Distance. Also, the gameplay is being tweaked to be closer to Kingdom Hearts II's - which should mean there's no need to fear the return of the first entry's temperamental camera.
