Why does everyone around here want to kill off plugins? There are some jobs they simply do much more efficiently than an html5+javascript solution. All of the Javascript-based PDF readers I've had the displeasure of using have been slow and buggy. Flash is nice for animations and some kinds of games (javascript + html5 games have in my experience always had little errors like misaligned text, key input issues with existing browser use, the browser highlighting parts of the game as if it's a text document, and the bigger issue of speed - they've always been slow on more complex games compared to the same amount of complexity in a flash game. This makes me highly doubt that an "HTML5 implementation of Flash" will take off within a few years. It would probably be just as bad as PDF.js.)
