progression to epub3 is inevitable. it is based on html 5 with more advanced css support and other elements such as audio and video,though both audio and video is iffy given that most up to date e-ink readers are doing away with audio ports and we know that e-ink can't really handle video. it should work fine on non-e-ink tablets, however.

I have seen some recent ePub that are trying to be ePub3 with backwards comparability with ePub2. But the really stupid thing is these ePub have no reason at all to be ePub3 as they don't offer anything that ePub2 doesn't. So why do it? Why bother to create ePub3 that's better off as ePub2?
I only found this out when I was editing one of them and managed to change something I thought was incorrect but turned out to be correct for ePub3.
