I don't know for sure why Mazda dropped the rotary. They claim they were too thirsty and drug down the corporate CAFE numbers.
The rotary we were working on at GM got dropped because of the difficulty of meeting emissions standards. We even had a version with a spark plug in the rotor to try to get it to burn cleaner.
