PlayStation Plus membership will carry over from PS3 to PS4
 

Just moments after baiting Microsoft with the PlayStation 4's less restrictive DRM policies, Sony announced that existing PlayStation Plus memberships will apply to all Sony gaming devices for no additional fee. "Members will have access to all the benefits across PlayStation 3, Vita and PlayStation 4 for one price," Tretton explained, sweetening the deal by outing a few of the free titles subscribers could expect to see in the coming year: Don't Starve, Outlast and Secret Ponchos. Naturally, Tretton summed up the PS Plus' major services as a steal at $5 a month -- just remember to buy in bulk, kids.
