Well PC’s went HD gaming and 3D gaming before Consoles so I’d imagine that multi screen gaming for consoles will eventually come along one day. Everything the PC does the consoles finally catch up with.
PC has always been cutting edge, first with pretty much everything we see in games consoles today in some shape or form. It was always said, if you want to see what the next gen of consoles will include, then look to the PC for inspiration.
Triple screen gaming is nice though, I’d love a triple screen setup with a steering wheel and pedals playing racing games, that would be a total blast I’d imagine.
Maybe PS4 will have enough power to do multi screen gaming…… who knows.
