There is a threshold of difficulty that some developers are just not willing to cross. Take the Saturn, for example. It has a twin Hitachi cpu for example that was quite difficult to program for. To my knowledge, the only company to have taken full advantage of both CPUs was Sega themselves. Most of the software simply did not take full advantage of the hardware. The story for the Saturn and the PS3 were uncannily similar (first 6 months). There was always the "just wait until developers figure out how to handle the dual cpu" and "sega just released a new dev kit to help developers take advantage of both CPUs" and so on. Sega didn't have the money to ride out the hardware storm and the games never came. Developers went elsewhere... Sony has a much larger prior install base and a rabid fan following so I'm sure they aren't going to fail in the long term as Sega did in the HW business but my point here is that Sony needs to get past the "difficult to develop for" stage before too many developers either go multi or give up altogether...
