Now this sounds promising:
Speaking at Gamefest, Microsoft hardware guru, Robert Walker
Texas Ranger, spoke of a possible redesign of the 360 controller. This "advanced" — and optional — control would be in lieu of keyboard and mouse support — something Microsoft still has no intention of doing. Thus, the new control would feature a redesigned right analog stick to allow for more precision, mouse-like movements. Naturally this controller would appeal mostly to gamers who prefer first person shooters and possibly RTS games.
