The Emotion Engine isn't actually the "main" chipset but rather the graphics interface utilized within the PS2s internal workings. The game's have a built in user interface and NPC interaction interface that has nothing to do with the emotion engine that runs the graphical capabilites of your PS2. The "Cell" is the "main" chip for the PS3(which is scheduled for mass production in late '05 to early '06) and the graphics interface will be a combination of 2 Emotion Engine chips working in parallel with each other creating about 10x the power. Well, i hope that you all enjoy posting and have fun gaming.
