One - the OP post is misleading as in fact he's saying the PS3 doesn't have a natural graphic advantage and that developers don't see value in leveraging its processing specs (which are more powerful). He's relating power to graphics and ignorning many other aspects of what 'power' could mean. He's also really relating it to ease of use/low cost as well.
Two - as with all the developer posts we've seen its centric to their own knowledge and experience. What's he's really saying is that when producing a multi-platform game the 360 is easier due to its SDK and approach vs PS3 (which is well known although a little out of date as new SDK for PS3 is available). He also shows he'd rather focus on a CPU/GPU architecture than PS3 Cell architecture - this is simply personal bias due to experience. Nothing wrong with it, but it also means taking his views on PS3 coding with a pinch of salt as he would clearly tail PS3 centric developers by a fair way in knowledge.
Three - given most multi-plats sell roughly same on PS3 install base as larger 360 the incentive should be there so I'm guessing he's not let near the actual running of the business as his comment makes no sense regarding sales (unless he's thinking US centric, which I suppose he might be but again this only makes clear he doesn't understand global picture)
So nothing new, another opinion for everyone to argue over, and the usual inconsistencies in message.
Try to be reasonable... its easier than you think...
