It looks like there is consideration for using ePub 3 books on ePub 2 devices, and the reverse of reading old book with new devices. The standard doesn't address the second path but I would expect the device manufactures to do so. The whole idea of HTML is to ignore things you don't understand. That has been the philosophy from the beginning and it should serve ePuB well. The standard provides for the older toc.ncx continuing support and the ability to work without script support and most other things will fall into the ignore category.
