I would need the 5 on its side but it's hoard to imagine how that's possible without a separate stand. It's almost unbelievable that they'd make a console like that.
But I think you're right that a lot of it is to sell new consoles. Just like making cars super fancy on the surface and mostly shipping the same internals. I'm sure the computer is more powerful and all, but how much more than the PS4 to justify it? Not enough IMO, especially now that I have a PC that can play new games if I want.
