I predict that it likely has between 160 and 320 Stream processors and the processor is running at ~2Ghz. The reason why I believe this is because the games don't look that much better than anything we have already seen and some of the developer complaints gave me a few hints IMO about the capabilities of the system. If it was packing something in the order of 640 to 800 stream processors, even with wickedly reduced clocks it'd have wiped the floor with the current generation consoles like you'd wipe your arse with toilet paper.
The reason why I believe that the console is 2Ghz or thereabouts is that developers did complain somewhat about fitting some of their code and if the cores are more capable then the only other possibility is that they are clocked slower. It is also quite a good clock speed generally in terms of power efficiency, just look at Intel Laptop CPUs. Nintendos OS is also likely far less efficient than the Microsoft OS and the tools are also far less developed, I would look for some quite strong improvement in the following 24 months. In the end it should look around 2-3* better than the 360 games by virtue of the increased RAM and more modern architecture.
The Xbox 360 had the rough *equivalent* of 240 but with a different architectural design, FYI for comparison.
Tease.
