You mean putting a shrunk EE+GS inside the Broadband Engine? Personally i dont see the point to waste die space for that. A shrunk EE+GS can easily sit on its own, if they really want it there. I think they'll go for software emulation, personally.

It is unlikely the PS3 will get the 8 SPE version of the Cell CPU as there are fabrication issues with that version at moment, and it will not likely be clocked at 4.6ghz that they was quoting at the CES. It is likely the PS3 will get a 4 SPE Cell CPU or possibily a 6 SPE Cell CPU. I do expect them to put the "Dragon" processor (EE+GS) in the PS3 for hardward backward compatibility as they cannot emulate the PS2 in software and if they do that it will have 4MB of embedded DRAM for the video part of that processor as the PS2's video had that much RAM. The only questions so far is how much RAM will the PS2 have (indications point to 128MB, though it could be as much as 256MB), how many of these Cell CPUs will they be using (it would be smart for Sony to have at least 2 in the PS3, one for normal tasks attached to 128MB of RAM, and a 2nd attached to their GS like GPU where much like the PS2 the Cell CPU handled the shaders and geometry and have it's own bank of 64MB or so of RAM in addition to another 16-32MB of embedded DRAM on the GPU which would only handle texturing and framebuffer... this is if Sony was smart.), and what nVidia's involvment with the development cooperation with Sony on the GPU going into the PS3 (I seriously doubt it will be a nVidia GPU, but rather a Sony made GPU with assistance from nVidia using some of nVidia's technology.)
Lots of questions, but hopefully will be answered soon enough.

Where did you hear that? Only trust reliable sources. The fact is it really does not matter if now, in March 2005, they are having certain difficulties. They have almost 12 months to figure that stuff out. While they never said the CELL shown was going into the PS3 (I think it is a safe bet) we may see other configurations, but at this point everything else is pure speculation.
Based on the XDR chips Samsung has in product 256MB looks like the most plausible canidate. I have heard of no indications that it would have 128MB of memory. That would be at least half of their competition (maybe even less depending on what Nintendo does) and would only be twice as much as the Xbox.
As for the memory structure, if the PS3 has 256MB of memory expect to see a unified memory architecture. 256MB is constraining to begin with, to split it in hald where the CPU has access to 128MB and the GPU access to 128MB would be extremely limiting.
Anyhow, E3 is in like 6 weeks so there is no real need to speculate much more
The real specs will be out shortly.JF_Aidan_Pryde

It's either four or eight SPEs due to Kuturagi's obsession with power of two. Four is too slow to compete effectively with XBOX so 8 it must be in the end.
EE+GS+IOP in one chip would be elegant.
