Here's the
FAQ from Paizo's site.
... A deluxe hardcover with foil-debossed faux-leather cover and ribbon bookmark, for a playtest book?
Original hard copy of the playtest is actually pretty rare so I can see why they'd want to make it collectors item this time around. Beta alone can go for $35.
They aren't being very smart with the playtest book, but hey a 2e to Pathfinder. I might give that a go and compare it with a leap into 5e given I've yet to play a campaign using DnD 5e.
This is similar to what Paizo did with the beta playtest for core rule book.
