Well right now the cap was changed from 512 MB of Ram to 4GB of RAM. That is a big jump. That 4 MB being a jump I wonder why they didn't go to 8 or 6, to maximize the ps4. Specs, or perhaps they still have to cater to low end PCs which still the early 64 bit PCs have 4 GB of Ram while newer PCs post 2012 have much higher RAM.
