Microsoft has bought a first-class seat on the Flash Bashing Express with an official statement on its IEBlog. Apple’s sometimes-friend, sometimes-foe echoed ideas that Apple CEO Steve Jobs expressed in Thursday’s Thoughts on Flash essay and put its own stake in the ground for the future of Web technologies.

Dean Hachamovitch, Microsoft’s General Manager of Internet Explorer, cut to the chase rather quickly, by stating “the future of the Web is HTML5.” He also said that Microsoft has been “deeply engaged” in the HTML5 process with the W3C, the standards body that drafts the specifications for how HTML5 should work. The company’s Internet Explorer 9, now in beta for Windows users, features HTML5 support. Hachamovitch says that while the W3C does not specify a video format for video embedded in HTML5 sites, Microsoft has joined Apple in supporting H.264, and H.264 alone.
