It was not good enough last week when Xbox One only have 5 GB available. Microsoft is behind, making box for non-gamers, bloated OS and not forward thinking and box already obsolete by awesome 7GB of PS4 super duper RAM.
Now that PS4 might have just 4.5GB, of course that is plenty for next gen. Sony is just being forward thinking so they can match Xbox One features by allocating more RAM for OS. Though to be clear Sony never copy Xbox and everything they did is better (even though they follow MS on everything from cross game chat, UI, achievements, and on-line games behind pay wall. Of course, the pay for on-line is now OK, because Sony need money for R&D and make things better, Microsoft on the other hand is greedy as fuck and ruin gaming).
I have a lot of problem with Xbox One especially the lack of BC and their unclear message on DRM, but seriously do some of you guys actually read what you write.
