Get off the Cell hype train and realise that just because the Cell is "more than twice as powerful as the xenon" that it is suddenly etter at everything. The Cell processor is quite simply not designed to handle AI. No amount of hype or development effort will fix this. You can make good AI for the Cell, but the Xenon will always have more potential.
Evidence suggests otherwise. If the SPEs are not used and a XBox 360 game engine uses multiple Xenon cores you may be right.
Note it's not as simple as breaking up an existing legacy game engine into pieces to utilize the Cell's SPEs.
That's why some developers have issues using their legacy game engines.
