Well, developers ain't gonna back down from photorealistic graphics, so they need to both address the storage capacity problems this generation in particular is going to experience (or already experiencing), and address the file sizes of games, especially like Call of Duty. I find it absolutely fascinating that I have so many beautiful looking games on my Switch and the vast majority of them are well under 20 gigs. Breath of the Wild is 12 gigabytes. Is it the best looking game ever? No. But I find art style so much more important than photorealism (rare exceptions, RDR2 for example is the best looking game on Earth imo) because it lends itself to 1) potentially smaller file sizes and 2) a more timeless aesthetic. Almost my entire Switch library fits on my 256GB SD card.
Just my aimless rambling here.
@Chino - ahh, understandable. Well, if you get an external and throw all your games onto the storage, you wouldn't have to worry about that anymore. That's another bonus of added storage.
