A major redesign does not appear to be on the cards, at least
Though Sony itself had previously admitted at this past E3 that the controller design for their PlayStation 3 console was not finalized, GameSpot believes any purported changes will not be substantial. They downplay a new rumor suggesting Sony will unveil a revamped PS3 controller at the Consumer Electronics Show in January 2006.
"...Sony Computer Entertainment corporate executive and chief technical officer Masayuki Chatanai told Famitsu after the E3 unveiling that the controller might undergo 'minor changes' but that the form factor would probably stay the same.You may not like the PS3 pad, and what you've seen so far may not be exactly it, but don't expect any kind of "Revolutionary" redesign on it before the system launches. Maybe a trigger here or some tweaked hand grips there, but it'll still look right at home hanging from a bright yellow utility belt.

Ah, but is the boomerang programmable???
