I never said the full game was coming out before MP4. It was pretty clear I was referring to part one. Yes, the gameplay was scrapped, but how long was they originally working on it before showing the original game in December 2019? This article https://www.dualshockers.com/final-fantasy-7-remake-news-2019/ makes it seem pretty clear that something is happening this year, and square is having a concert right around e3 this year just for FF7. Remeber, this is a new game vs a remake, and without fact checking, I think it is safe to say that Square is bigger than retro.
However, show a bit or even a lot this year doesn't mean it will come out soon, just like the gameplay footage they showed in 2015, all became meaningless.
