Is there a basic size unit for font or for layout design(You will find percentage,px,pt,em system none reliable here)

A standard away from reality is meaningless.
ePub 3 is based on HTML5 and HTML5 supports audio and video. The early adopters of ePub 3 so far have been children's books in fixed layout ePub and for this audience audio and video may make a little sense.

But I agree which the detractors that essential features need solutions but are being ignored. Even ePub 1 (Open eBook) had better features (for example headers and footers) in some cases than anything since.
