I think my E3 prediction was not too bad :)
That said, I think most people were pretty clear in their wording that it always was E3 2020 which will be important. E3 19 was just too early for most of the XGS studios.
However, this by no means translates to E3 being a bad show or anything. On the contrary I think it was a solid show - with expectations being too high (like always to be honest ...), despite various people reminding you that they won't show their big guns - including PG#2, Ninja Theory SP game, Rare etc. - this year. There were more than enough posts here reminding everyone that it doesn't make too much sense to blow all your stuff this year, when in reality it's the next year where people will make their purchase decisions for next-gen.
34 games launching into Game Pass day and date - including anticipated games like Gears 5 UE, The Outer Worlds, Wasteland 3, Blair Witch or Psychonauts 2 - was an impressive statement though.
