Yeah, I read it all.
The missing part basically boils down to "yes, the SPUs are great but parallelizing is hard, so it is easier if the GPU can do everything _really fast_". Again, it's a divide that will never heal between those that stick to the PC way and those that are accepting to spearhead the hard work on parallel processing.
I wonder what the same developer thought when programmable shaders came up.
Btw, I think that dates back to October 2007. The same developer would probably not say the same things about PS3 exclusives sucking nowadays. Maybe some of his ideas about what is viable development would be different in their light.
