Flight simulator is not a broad title. It is literally for people interested in flight simulation. like you can actually almost get legit experience doing flight simulator for actually flying. Gears tactics is a RTS/Xcom type game thats not super broad either.
Medium looks like it could fit that Alan wake type of mold and be a sleeper hit to be honest. It looks really cool.
Your last part answered my question. They dont have any big games that look like 2021 releases. Few smaller titles like the gunk, warhammer but those are not system sellers.
Sony literally has one of the most stacked 12 months of a console launch I've ever seen. It's PS2 2001 all over again.
Returnal, Kena, RATCHET, Destruction All stars, stray, Demons Souls, GT7, Horizon:FW, miles morales, sackboy adventure, ghostwire. All launch/launch window. Deathloop sounds like it could slip though into later 2021.
I'm not even touching Japanese games that supposedly might launch next year as well. Like FF XVI.
