And not just you.
I agree so far as: IF they break compatibility, which they seem firm on, they better make a game that appeals to customers used to 5E sensibilities.
As you yourself illustrate, just appealing to PF1 fans might not be good enough, especially given the lack of backwards compatibility.
PF2 doesn't need to be 5E, but I think they need to take a page from the more simple math of 5E, or even the OSR games. Things like micro feats, prestige classes, and perhaps magic item mart need to stay in but some items need to be trimmed or errated. Wands of CLW either don't exist or are custom items. PFS still a thing (in terms of people actually turn up and play).
