Two of the major challenges displacing PPT with interactive tools, particularly in consulting, market research type of business, where large 100+ slide decks are common, are going to be the (1) need to produce decks on clients' templates and (2) need to email decks.
The direction in which a few emerging CSS/JS based tools (slides, reveal, etc) are going will not solve that problem. D3/WebGL etc. are awesome, of course, for the web. However it's relatively rare when a busy exec will have time to use non PPT based deck.
I agree with your sentiment about email, and wanted to add that the major reason for this is still a fear of lack of Internet. There has never been a meeting I've attended in ~20 years where we didn't have a backup plan if we had no Internet. This still looks like a solutions that needs the Internet to work. MS would do well to make these formats offline and open-able with the next version of PPT. Take that to the bank!
