The problem with ePub 3 is all the multimedia stuff that has been added in. A lot of ePub is read on eInk which a lot of eInk readers won't handle well. What would have been better is the multimedia not added in and the other improvements kept. Then it would be a lot easier to upgrade. But until Adobe upgrades and most of the Readers get upgraded, it's not going to fly.
