Listings for the PS5 console have appeared on the pages of Amazon UK. The next-gen hardware was apparently priced at £599.99 (US$764). More surprisingly, this was the same listed price for both a 1 TB and 2 TB variant of the upcoming PlayStation 5 device. A whole host of PS5 games were also listed on the same website.

2 TB version would have more than 1.65 TB storage. The smaller storage on the 1 TB version likely accounts for the OS and system files. They wouldn't need to be stored on the other TB. So it'd likely have over 1.8 TB free, not simply 2x the 1 TB version
