Don’t care. I have a 4TB hard drive.
Love the games with a lot of details!!
I have a 10TB Hard Drive and it's only got 30% space left.
Things will only get bigger. Next gen most games will surpass 50-60GB easily and some of them will hit the 200 GB mark. Requiring 2 100GB BD discs.
Since PS5 supposedly only has a 1TB SSD, I'm not sure the leap will be that big.
In fact, since we'll get the option to chose which parts of a game we want to install, and un-install after we are done with them (remove the single player mode and only keep the multiplayer mode for example), disc space management may become less of a hassle.
Next-gen could remain static with it's file sizes.
Audio and Video encoding has improved substantially over the last few years thanks to the likes of HEVC. - Which the current base Xbox One and Playstation 4 generally cannot decode natively within hardware, but next-gen should. (VP9 and H.265/HEVC.) - That could reduce video and audio file sizes by 50% or more at the same quality.
And of course games will still come via Physical on Blu-Ray.
Plus... We don't know how large the SSD on next-gen consoles is, it may only be 500GB for a base variant with a 1 Terabyte variant as a higher tier.
