I hope they do dedicate 2-3GB towards the OS and just put more ram in the system. MS is a software company and have shown that they know how to make a much better dedicated software OS then Sonys pos from last gen and half ass ps4 concept. a newer built up live 3.0 and 2-3 gigs
Having more of the 8GB of RAM dedicated to the OS is just making the console less capable for games since you're chopping off 2-3 GB for just reserved for the dash and stuff. Not to mention it's DDR3 RAM as opposed to Sony's DDR5.
Am I really right that you want 5GB of DDR3 as opposed to 7.5 DDR5?
