The momentum towards HTML5 and away from (or at least in parallel with) Flash seems to be accelerating with today's launch of the free Brightcove Experience framework for HTML5 -- a "way to publish, distribute, and monetize web video for the iPad and other Apple devices" according to the Brightcove press release. While Brightcove might not be a household name, some of its 1,000 customers, including Time Inc. and The New York Times (a Brightcove investor), certainly are -- both of whom are already using the new HTML5 solution in preparation for the iPad's April 3rd US launch. A real coup for the Flash-hating Steve Jobs if you start factoring in the rumored Flash-free NPR and Wall Street Journal iPad sites as well as that little HTML5 iPad test CBS was testing out in the open last week.Also rumored for launch is an iBookstore filled with 30,000 free e-Books courtesy of the Gutenberg Project. See the screengrab evidence after the break in addition to a purported video walkthrough of the iPad store. The video previews several new "HD" formatted iPad apps that we've already seen as well as a few new ones like Twitterific. Sorry, still no Hulu HD. The mouse pointer in the video, however, makes it clear that this is running on desktop somewhere, not on an iPad. Still, it definitely looks the part.
