Following yesterday’s unsubstantiated rumours that the PlayStation 4 may have a Digital Rights Management system that prohibits second-hand game sales, Wedbush Morgan’s Michael Pachter has said retailers would refuse to stock or support such a console.

“It isn't really in Sony's or Microsoft's best interests to block used games. It would benefit Activision and EA slightly, and would hurt GameStop a great deal. If Sony unilaterally did this, I could see GameStop refusing to carry their console, and sales of the PS4 would therefore suffer,” believes Pachter.

Pachter pointed out, “If one does it and the others don't, the one who does it will see a loss of market share.” He added that none of the Big Three platform holders are “stupid enough” to do so unilaterally or “evil enough” to do it together.

David Cole of DFC Intelligence agreed, adding that blocking second-hand sales would drastically impact on the core gamer market who frequently trade in recent releases in order to buy new releases.

“A system that tried to stop used game sales would probably turn off the core consumers that rush to trade in their old product to buy new product. In other words, I don't think it would do so well in the core market,” he said.

Sony has not commented on the latest PlayStation 4 rumours.
