1) Webkit and EPUB3 have nothing to do with each other. One is a rendering system used by many epub reading devices (or reading applications) and the other is an open spec that tries to define how ebooks should be structured. And EPUB3 added much in the way of metadata and semantics. You can't however, force people to implement them in their books or reading systems.
2) A very large number of commercially sold epubs are sold as epub3s. I buy them all the time. EPUB3 is very much "in the wild." Has been for some time, now.
