just two things I want to add to this discussion: 1) PS3 has 256MB RAM. You don't add your video RAM to your PC's RAM do you? No, because video RAM is very specialised and can only be used for certain things. Same with PS3. So definitely 256 MB RAM. However, at the same time, it is unfair to say Xbox 360 has double the RAM, since its 512 is shared between the video and the CPU. Most likely it'll be split 50/50 by many developers anyway. 2) While AI is very computer intensive, it takes very different types of computers to do AI. While the CELL looks very good in terms of raw processing power, which could make for very powerful physics/graphics calculations, but the CELL is definitely not designed for AI, which requires lots of branch prediction and other things which are useless for physics and graphics. The SPE's are basically useless in this case, and the AI will have to be handled completely by the PPE, making it essentially worse than the Xbox360 for AI, and not incredibly more powerful than the Wii.
Help! I'm stuck in a forum signature!
