6600 BB for Double/Triple Question

Per the Shimano website, when displaying the 6603 gruppo, it lists the BB as a 6600. Is there a specific BB for a triple for the 6603 or will the 6600 BB work?

I'm thinking that since the spindle is built in to the crank itself, the bottom bracket cups could be made to one size, the only difference would be English or Italian threading. If what I'm saying is true, could you use Dura Ace BB cups too, and would there be any difference?
