MRAM! (Magic RAM!)

It's a great question. May I suggest you make a poll in this thread.
GDDR-4 seems the most likely choice with its speed and density. I haven't read any detailed info on GDDR-4 but is obviously the next evolutionary step of GDDR-3. ATI designed the memory controller for the Xbox 2 and they're most familar with this class of memory.
I suppose the wild card would be some sort of Quad Band Memory version of GDDR-X.
My guess would be 512mb of GDDR-4.

Yeah well PS3 will have twice as much as what's in that picture!

Internal changes to GDDR-3 to get a higher clock speed. The changes will probably be a trade-off of increasing latency.
Na , i think they will use gddr-3 ram at speeds we currently have with much lower latencys which i think will help out the umd nature more than higher clock speeds
If the 'leaked' diagram showing 22.4GB/s bandwidth is accurate, I can't see Xenon's main ram being anything other than 700mhz 128-bit GDDR3 or 4. In light of Brimstone's comments about GDDR4, I'd guess GDDR3 would be better.
Apologies if this is stating the obvious. Or already known to be untrue.

Well I'm guessing that GDDR-4 will have increased latency. DDR II has a more latency than DDR, I guess then it safe to assume the same thing will happen with GDDR-4. The great news is that the clock speed will be higher resulting in more bandwidth per pin. Multimedia applications tend to be "stream" based, so bandwidth is king.
