A Japanese seller active on Yahoo Auctions has been listing PlayStation 5 prototypes consoles—their time limited (24 hour) offerings have probably been implemented to dodge the wrath of Sony Corporation's legal team. A "Prototype 2—not for sale" devkit was made available last week and eventually sold for around $5500 (JP¥ 800,000). A "Prototype 1" unit was purchased for JP¥551,000 (~$3810) over the weekend, and another auction was created this morning—the unmarked system started off at JP¥600,000 (~$4150). The seller has gained some notoriety within the enthusiast scene, due to their acquisition of other rare bits of hardware, including PSP development kits.

It is believed that these PS5 prototypes pre-date the devkit that leaked prior to PlayStation 5's official launch, so hardcore collectors could be enticed by the prospect of owning unusual items. Sony's very thorough tracing system will likely result in these units being unusable, but members of the gaming community are puzzled by the corporation's lack of action—given the seller's ability to acquire and sell all sorts of PlayStation development equipment, with vintages from over a decade ago.
