The big problem now is indeed the memory constraints on the PS3. 256 MB is simply way too small for graphics nowadays. Imagine being a multiplat developer applying textures to your game on the PC dev kit (They nearly all are for multiplat) and constantly having a PS3 Texture limit reached warning crop up.
I honestly think the PS3 is a great machine held back by some terrible design choices. I expect the PS4 to have all these problems rectified.

OK, but how much of the 360's memory (over 256) can really be counted on? (Honest question -- I'm curious and don't know.) It's not like the CPU doesn't take any. Definitely there is advantage to the 360 there, but it's not like the 360's memory is impressive compared to PC memory either.

as much as the developer wants to allocate rather than being constrained to up to 256 for CPU and 256 for GPU* like the PS3, on the 360 if the developer wants to allocate 400MB to graphics then they can do that as long as they don't need the memory for something else and if the game needs more for CPU tasks then they can do that as well and the changes can can be made on the fly as well so if one level needs extra textures but has less physics then the system can do that. Which is one of the reasons why the 360 is easier to develop on.
* On the PS3 it is actually possible for the Cell to access VRAM and the GPU to access main RAM so devs can use the CELL for rendering tasks but it incurs a performance penalty from what I have read.

That sounds great for cinematics, but I'd think that you'd usually want your nice graphics to go along with nice action. So, to make this pertinent to the question I asked, is 400 MB a NORMAL amount to have on one side of the fence, and 100 on the other? For gameplay, I mean?
But thanks for the info about the PS3 being able to shift memory (at a penalty), I didn't know that.

but that's the point there is no normal every engine and game will be different and even in one game it can shift depending on what's going on. As it is so fluid I don't think any devs have (if they even could) reveal what the split is like. The closest thing would probably be when the Epic guys said that Gears 2 couldn't run on PS3 because they used more than 256MB for graphics.
