I can see Hades or ACNH taking GOTY. Hades because its become this beloved indie that a grand number of game journalists and the public have grown to love recently while ANCH is the one game on that list that got many different people into playing video games more so than any of those other games this year. But I do still think TLOU2 will eventually win the award since 1, people think recent bias wins these awards while the last 5 GOTY winners (From Witcher 3 to Sekiro) were all 1st half of the year game releases. Secondly, it doesn't get as prestige gaming as it gets with TLOU2 and while I haven't played it, I know its definitely a huge critical darling so I think it will take GOTY. Rooting for either ACNH or Hades because well, those are the only two GOTY nominations I played and I don't have a PS4.
For predictions on announcements, I think we'll see footage from one of Sony's big upcoming exclusives for PS5 (Thinking a toss up between Ratchet, Returnal or Horizon FW).
