A rumour it'll have an NVME. Highly doubt it. It'll just be a normal SSD i reckon, and either in 1TB or 2TB sizes. Either way it still isn't enough with most games now exceeding 50GB. Not sure about the 8K stuff either. If anything it'll be able to play 8K content (movies/video) not games. The current ps4 pro can't even play native 4K games as is. DEVs still haven't learnt that people just want a smooth 60fps gaming experience. The 30fps cap kills it for me hence why I don't really buy games on ps4 so if there is one thing i'd like to see is 1080p-1440p max settings at 60fps.
