I would take this with a grain of salt just because Matsuno doesn't work at square enix, you would hope he would be involved in a remaster or at least know it was happening, but that's not always how these things play out
If you're developing a remaster of a game while you have the director of the original game on the payroll, that's not a breakdown in communication. That's intentionally keeping him out of the loop.
Trust me, I'd love it if you were right on this, but as far as I'm concerned, this means the leak wasn't accurate in this case or the project got axed.
