BluePoint was working on more than one game.
Sony is timing the 1st part acquisition announcement with the new game.
They were working on more than one game, the game will come out in 2022, and people who follow the ARG/Pre-order get a PS5 version of P.T. that day.
It's an ultra-linear, 7 hour game, that could be re-made by them in a year maybe two.
Metal Gear Solid in 2023/2024 near the release of the movie with Kojima's oversight and blessing.
They could create a streamlined development pipeline for re-creating two Konami, PS1 games back to back. Meanwhile, Sony is foaming at the mouth to charge $70 for a game that needs no concept art, writing, character development, or massive investments into developing a new IP.
Just my guess after seeing the .gif.
