8 gigs of GDDR5 ram (ie. better than most people's PC. That includes pc gaming enthusiasts)I didn't stay up last night cos I'm a wuss who needs my sleep. Go to Gaming Side - is there a sticky with screens and specs? No, there's a million posts of idiots pondering imponderables. This is what I hate most about the gaming internets, armchair experts spouting crap. They're worse than football fans talking about transfers.
As of now I have no idea what the PS4 is. I saw a gif of a shiny city, looked alright.
x86 CPU, 8 cores
Modified ("improved") PC GPU
Share button on controller - ability to instantly live-stream games, or save gameplay videos, or have friends jump in and take over controlling. All handled on the OS level.
Gakai streaming backwards compatibility at "some point in the future" (ie. forget about play timing-important games)
Controller has PS Move-like abilities built into it, but isn't a replacement for Move
Controller has touchscreen and new triggers
New inFamous game (yay!)
New Killzone game (looked like a pretty Call of Duty set in the future)
New kiddy platformer by the guy who worked on Crash Bandicoot, Spyro and other quality kiddy platformers (possible yay!)
Watch Dogs is a launch title (and it's going to WiiU too)
Destiny (Bungie's new game) will have PS4 exclusive content
Diablo III coming to PS4 and PS3 (good news for anyone who has an awful PC/Mac, otherwise yawn)
John Blow's The Witness is coming to PS4 (was the first genuinely super-exciting game of the conference)
Media Molicule showed off their new content-creation tools to be used in whatever their next game is (didn't show any of said game). They used the Move controller to sculpt in 3D space and then play a Rock-Band like game. It looks good.
Square Enix came on stage to show you an old tech demo and to announce they will be announcing a new Final Fantasy at E3 (seriously)
It does Netflix (megaton)
I think that about covers everything...
In conclusion: well done to Sony for actually showing games. PS4 has my interest more than the WiiU right now. Not quite at a stage I would buy one if it were available yet.
In proper conclusion: it'll soon be time to upgrade your PC, as we're finally about to emerge from the five year PC consumer tech stagnation.
