a bit more about the update
Sora and the other character models for Kingdom Hearts have been replaced with character models from Kingdom Hearts 3D: Dream Drop Distance. And play operation is closer to Kingdom Hearts II. Regarding the Theater Mode, 70 percent are mainly old scenes made to be new cutscenes with voice.
“Is there gonna be a high-definition version of Kingdom Hearts II later?” asked Famitsu.
“It’d be unusual if there wasn’t,” Nomura replied with a smile.
still no word on what regions it is going to be released in though.
