I know dates and priorities change, and since you have been very dynamic in your response to your userbase I envision a list where things appear and float up/down, as well as a sidebar for 'tabled' enhancements that haven't made it on the calendar, or fall off the calendar for various reasons, which could be briefly explained. You could even format it to allow viewers to vote for their favorite, helping to prioritize the list.
And what a selling point, demonstrating the excellent responsiveness that everyone who owns the product already knows. It would also act as a staging area for the features descriptions used once a product is released.
How cool is that?
