It would sell and be a big hit and make sense, so Sony won't do it. Seems to be the sony way.
Except it wouldn't be Sony's call. Square Enix is in charge of deciding where do their IPs land and they said they want KH to return to actual consoles. Go and moan to them~.
Personally I would love an hd collection to be announced at tgs. Been so long since I played kingdom hearts
I would like it because I never played any of the games when they were originally released on the PlayStation 2.
