An interesting note from Mark Cerny's talk, a lot of games have multiple copies of data installed to keep locality when loading up say a region of the game world, with the way SSD reads work they won't have to do that anymore which should cut down sizes, though how much I don't know if they have figured out yet.

I'm sure the SSD will get bigger on later revisions, and they are having support for expandable storage which should come down in price over the lifetime of the console.

That was the promise for the last generation of consoles as well, and some of their generation-closing consoles still had small internal storage quantities; the launch PS4 had 500GB, and the latest PS4 Pro only has 1TB (about 150GB more than the PS5).

I could see that happening, but on the discounted revisions. At the same price over time I’d expect more storage.

You can put an off-the-shelf SSD into your PS4.

Does it matter that much when you can connect a 5TB+ external drive (or upgrade the internal drive trivially on PS4)?

That is my biggest problem with it too. Sony and MS need to crack down on that. We don't need 4k assets. We're not f'ing there yet. Quit making us all have to download them.

? A significant portion of Xbox One X games are native 4k
