@GrailUK That's one of the possibilities I expect from Sony.

I think most likely, PS5 will just be a more powerful PS4 Pro, which was just a more powerful PS3, which was just a more powerful PS2... They'll just double down once again with significant upgrade on their existing hardware that wont really offer anything new. Although it will probably play 4K blue ray movies. It will probably still support PSVR, but VR wont be the focus.

Second most likely I think they will make the PS5 be the "PS Swap" and just rip off Nintendo like they did with the Playstation Move. It'll be a glaring knock off just like the Move was. And just like the move, it'll have more powerful hardware. But unlike the move, I think this would be highly successful. I suspect Sony could make their hybrid be comparable to the current PS4 Pro for not much more money. They'd probably take a loss at first, but it would still sell very well and do well in the long run.

3rd most likely I think is Sony goes all in on VR and makes the PS5 totally focused on VR. I would have ranked this higher than the Swap if you asked me last year, but it seems like the VR hype is finally dying. It failed to take off despite all the hype it had initially. However considering when the PS5 likely began development, I still think there is a good chance they will go this route.

I think the least likely thing for Sony to do is to innovate at all. Sony never innovates with gaming. They haven't since the original PS1 which was a result of their failed partnership with Nintendo. Sony's entire history with gaming is taking ideas other people have pioneered and trying to push them as far as they can. The best graphics on a dedicated home console is the standard operating procedure. I like Sony too, but they don't know HOW to make something new and original when it comes to gaming.
