I suppose 98% of the rest 2% can be done today in HTML5.
Yup, just as long as you are willing to give up any sense of decent UI, performance, etc. Mobile devices are shockingly bad at rendering HTML at a good rate, and I'm yet to see a HTML5 page that properly scales to different screen sizes, has good information density, or works properlly offline.
That's not to say these things aren't possible, but I have to assume that they are very hard because nobody seems to be doing them.
