psx (1994) - 1mb vram, 2mb main ram (3mb total)
ps2 (2000) - 4mb vram, 32mb system ram (36mb total)
ps3 (2006) - 256mb vram, 256mb main ram (512mb total)
That's an order of magnitude increase every six years, and this generation will last longer than six years.
For next-gen, 8gb is on the high side but not out of the realm of possibility. And of course the developers are going to lobby for as much as they can get, same as they do every generation. Cliffy would cream himself if MS announced an 8gb machine.
