I respectfully suggest that if a major product announcement turns on a feature that isn't yet ready at the time of the announcement, failing to listen amount to executive incompetence. They need to listen, and even if they are told that everything will work, they need to ask probing questions to make sure. A company that chooses to manufacture a demo of software that can't yet do the things shown the demo is putting its credibility on the line, and it needs to be damn sure that it will be able to provide the feature it is advertising.
