Microsoft is supporting H.264 in IE9 but not its own system, VC-1, or the open source Ogg Theora. It will continue to not support Adobe Flash, though you can expect it to support its own rival system, Silverlight.
Microsoft's Dean Hachamovitch, the general manager of Internet Explorer, says he has noticed "a lot of posting about video and video formats on the web recently," and taken the opportunity to chip in with support for the H.264 codec. He writes:
HTML5 will be very important in advancing rich, interactive web applications and site design. The HTML5 specification describes video support without specifying a particular video format. We think H.264 is an excellent format. In its HTML5 support, IE9 will support playback of H.264 video only.
There's nothing new about Microsoft supporting HTML5, even though it's not yet a standard. There's also nothing new about Microsoft supporting the heavily patent-encumbered H.264. Nonetheless, some people have taken the "only" bit rather badly, saying that IE9 should support the open source codec Ogg Theora.
