There's about a zero percent chance of that happening. Borneo, Australia, Pearls, All-Stars, Vanuatu and Palau were all released in retail stores, while the rest have been/are being released via Amazon's Manufacture On Demand program (sets aren't printed in bulk, but are instead burned on high-quality DVR discs when you order them. don't mistake it for bootlegs, these are 100% authorized by CBS).
