Don't expect something drastic like 2 TF or more RAM. The numbers that we are looking at right now are on the optimistic side. The best case scenario for me is IF Sony can hit the 1.843 TF number alongside 192 GB/S RAM with a nonbloated OS.
I'm not expect miracles, but final devkits are supposed to come soon. I'm sure some folks here will pipe in at that time.
Weren't final devkits for ps4 supposed to come out this upcoming summer? Or has that changed now and they are coming out sooner?
