havent heard about it, but im not surprised- eventually every new car will have to be a hybrid- unless it gets at least 40mpg. ive heard soooo many people digging the prius because of the money savings in terms of gas!
Toyota/Lexus plans to launch the RX330with a hybrid derivative (RX400H) this fall. It's rumoured that the Highlander will follow shorlty after. If these projects are successful, making the Camry a hybrid isn't too far fetched an idea.
