But what the developer is talking... about memory... I think it is the biggest ever... GPU performance I'm not sure.

Anybody remember a increase in 16x the size of memory from the previous gen???

Maybe in terms of pixels, teraflops, gigahertz, RAM, memory, [insert more technical jargon], etc. But it doesn't look like it at all, at least not with my eyes. Most of the games shown looked like super-polished PS3 games, for the videos that actually showed gameplay. I guess that's one effect when graphics become so good that further advancements can't be noticed by the human eye. I believe the PS1 --> PS2 and PS2 --> PS3 were much more impressive.

Of course this is based on what was shown so far. I'll need to play it on an HDTV for my final judgement. And I will also have to wait for later games. Though I doubt I would have the ability to truly appreciate the entirety of the advancement.

PS2 to PS3 was a 16x jump (32mb to 512mb).

Quantum Conundrum is best selling?

In fact 32MB system RAM, 4MB VRAM, 2MB Sound RAM, 2MB I/O RAM... so 40MB RAM.

~13x PS2 to PS3.

Didn't each PS console increase the memory 16x.  I saw someone post it, but don't know if it's true.

Ah, I overlooked the "other" ram. I'm pretty sure the PS1 had less than 1/16 of the PS2's memory, though, but I'd best double check that.

Great. Sony should aim for having the strongest console ever.

Ps3 launch games looked like super polished ps2 games. For example GoW2 looked great on ps2 and genji and untold legends were a slight step up from that... i think people are wayyyy to use to the 7 years devs had to maximize the Ps3.

Using only the video and system RAM:

PS: 3MB
PS2: 36MB (+12x)
PS3: 512MB (+14x)
PS4: 8GB (+16x)

But infact the PS (3.5MB total) and PS2 (40MB total) have addicional memory for each hardware part (Sound, I/O, ect) and the PS3 and PS4 have a unified pool for all hardware.
