Just to be clear, Paizo definitely isn’t (re)printing any more PF1 hardcovers. The only PF1 products they’re printing are pocket editions of PF1 rulebooks that have sold out.
FWIW, here’s what they’ve said about PF1 support, moving forward:
“We've poured our hearts and souls into Pathfinder First Edition over the last decade, and we're thrilled that gamers are so loyal to that expression of the game. While we do not plan to release additional Pathfinder First Edition products after August 2019, we DO plan to keep paperback Pocket Editions of First Edition rulebooks in print as long as enough people are buying them, so even in the era of Pathfinder Second Edition, First Edition adherents should be able to find their preferred version of the game in print without too much trouble. Our First Edition PDF products will also remain available.”
