Yes, but I would hold off on buying any rulebooks until the remaster comes out. All of the rules are free online, and the Pathbuilder app/website is very helpful in seeing which options are available for you. If you want a good starting point, I recommend an adventure path, which is a 3 or 6 book campaign that takes you from levels 1-20 (six book) or levels 1-10 or 10-20 (three books). They’re much better than the published adventures for some other games, since Paizo’s history is in writing adventures, and they don’t require much work beyond what is in the book for a satisfying story and adventure. Those are fine to buy, since they are compatible with the new version and they will not be reissued later. Same with setting materials, which are extensive and have a good amount of detail on various places in the world. I’d try things out in roll20 or foundry, which have the base rules integrated for free, and see if you like it.
