Also, knowing the console manufacturers they will put in a 64GB or 128GB SSD that you can 'expand' or 'swap out'.
Assuming next-gen games will be at least 4K, you would probably fit like one game on a 128GB SSD.
It will be some hybrid thing, where the ssd loads in your most used files from the standard hdd. Should work alright.
I don't think games will change that much in size either, not like resolution matters to the game size, despite the best attempts at 4k texture buzzwords.
Well...
1. A real 4K game would not just be a resolution bump, but also a texture bump, higher quality game assets, etc.
2. 4K video if and when it is used, would dramatically increase the size.
3. If you look at the download size of games between this generation and last generation, they have doubled. More than doubled in some cases.
Considering some games on my PS4 are over 60GB, I fully expect there to be games that exceed 100GB on the PS5.
