I already own a Switch, and I have thr Series X on pre order. Provided that stock allows it to be shipped before 2021, the PS5 will be the only missing console of the trifecta. I am not concerned about that one till the next God of War drops (likely to be delayed to 2022 or later), since I can play Horizon 2 on my PS4 Pro.
As for your bonus question, pre ordering a Series X was a fking nightmare. I will leave it at that.
