Paizo is in an interesting position regarding competition in the TRPG market. A lot of us have spent a fair bit of time playing Pathfinder, and have migrated to 5e because the new version of D&D has the right mix of elegant simplicity and nostalgic flavor. The truth is, however, that I--and I'm sure I'm not alone in this--actually miss Paizo.
I like, genuinely, Chris Perkins and Mike Mearls. I like Jeremy Crawford, even if he did make some rule interpretations I know are wrong. I like the D&D 5e product line, in spite of some inevitable flaws. What I don't like is WotC/Hasbro. There's a sense I get that Hasbro doesn't understand D&D, and only thinks of it as a side gig for the MtG business unit. I get the feeling that there is a sort of animosity towards the RPG community lurking in the corner offices, that informs and influences their decisions on things like the sale of pdf versions of their current edition books and their treatment of community created tools like character generators. You can say what you want to about their "legal right" to make those decisions--I'm not disputing that. I'm just saying that often, in important ways, Paizo has made different choices and earned my affection because of it. In fact, returning to D&D with 5e has made me appreciate Paizo even more, even while I absolutely prefer 5e over Pathfinder.
I don't know whether I'll switch over to PF2, or what it would take for me to seriously consider it. I do know that I'll eagerly check out the playtest, and when the books hit the market I'll buy the core PF2 system books unless it somehow has become a shocking trainwreck of a game (which seems unlikely.) I'll buy them (probably hardcover, pdf, and Fantasy Grounds) for two reasons: one is that even if I don't switch systems, PF2 will probably have a polished system for creating magic items as well as some other mechanics that I'll be able to apply to my 5e games. The second reason is that I like Paizo, and I want to support them.
