My response to all three of your numbered points is "No, not really."

1) For the vast majority of ebooks being sold today by major publishers, releasing those books in the EPUB3 format has not, in fact, required new hardware.

2) For the vast majority of ebooks being sold today by major publishers, releasing those books in the EPUB3 format has not, in fact, required new software.

3) EPUB3 has never been synonymous with "multi-media ebooks". Those who think multi-media ebooks are a monstrous abomination have merely perpetuated that particular misconception is all.

EPUB3 allows new things to be utilized. It doesn't force them to be utilized. It's adoption will not be the death-knell of text-only books.
