I've read about it, and basically Adobe already knows that Flash for the web will be dead in the coming years. I think this is a good thing, I'm getting tired of steaming videos that don't work on some sites, HTML5 will solve this. And I didn't even know that you can also build games in HTML5: http://www.webdesignerdepot.com/2013/10/30-incredibly-addictive-html5-games/ http://html5games.com/
I also noticed that a lot of websites use HTML5 video in a cool way, but the format is WebP, I don't know if media players can handle this: http://www.titanfall.com/
