It appears as if the PS4 will allow games with split-screen co-op to play across two TVs while using only one copy of the game, thanks to the VitaTV and Remote Play. While playing via Remote Play a second player can join the game on the PS4, essentially meaning you could be gaming on two TVs in different rooms with only one PS4, one copy of the game and one VitaTV.
SCE Worldwide Studios President Shuhei Yoshida confirmed the cool feature in a tweet last week
By the looks of things, it seems the ultimate setup if you’re a PlayStation fan will not only be a PS4, but a PS Vita and a VitaTV. Apparently the feature was considered with games like Knack in mind, but we’ve yet to see any footage of this two TV setup yet.
