MS came out pre-E3 and right from the off, said that the XB1 was not just about the games, but also about:
"TV! TV! TV! TV! SPORTS! TV! SPORTS!".
And, they threw the gamers a bone, "CALL OF DUTY DOG!"
The response? They were panned for allocating hardware resources to something other then games. Personally I'd thought it was a smart move. Still do, I've had my XB1 on pre-order for months. I want more than a games machine sitting under my TV for next-gen.
Now, Sony (wisely I'd say) are doing the same - allocating hardware and memory so the PS4 too can (potentially) do:
"TV! TV! TV! TV! SPORTS! TV! SPORTS!"
....and anything else that becomes popular over the lifetime of the console.
The response? A near-collective shrug of the shoulders and "No big deal, nothing has changed here."
That's.....interesting.
If Sony are guilty of anything, its not coming out before now and telling people that its not just about the games for PS4. Either way. 5 to 5.5Gb of RAM should be enough for some decent games, regardless of what console you buy.
It also means that Sony can now go toe-to-toe with MS for the non-game features. That's good, for everyone. Nothing wrong with competition.
