I'd imagine it's some kind of RTOS to handle the time sensitive parts of the graphics / AR stuff. Probably not custom kernel but they'd have to develop a lot of stuff around it. As for the sales platform, why wouldn't they develop it? To attract developers they need to make it easy for users to buy the products those developers would be create. It's not like the early 2000's where you could launch a console without an online store, it's pretty much mandatory these days because both developers/publishers and consumers expect it to be there.
