Publish to HTML5 from Illustrator using plugin

This is cool, HTML5 canvas support for Illustrator:

The content displays and animates flawlessly. What’s totally cool about this plugin is that it almost turns Adobe Illustrator into Adobe Flash Professional—only it publishes to HTML5 instead of SWF. It kind of blows your mind.

Wonder if this HTML5 stuff is going to be around for the long haul or if its just a fad... already seen a few job ads for specifically HTML5 developers even though its only just been released far as I know.
