So I saw the live stream at 6pm EST. All I have in my head now is 3 things. 1. PS4 2. Holiday 3. 2013
I'll recap some special points I really liked.
AMD 8core cpu (forgot the full name lol, just read the post before mine)
GPU (again read up top
Memory 8gb nice!
There was a scene that showed a demo in which a million 1,000,000 objects spawned in at the same time and there was 0 lag. Basically games like WoW and Diablo that have amazing cinematics, those cinematics is basically the game on the ps4.
Really all I can say is watch it for yourself its really worth it
