MPEG LA Announces Call for Patents Essential to VP8 Video Codec

I guess it depends on if "support" means that they are all for it and plan to do everything they can to make it successful or if you limit "support" to mean that the current release has the capability.

What is taking them so long? Well, it is simply taking them a long time to release Firefox 4. The delay with WebM is entirely incidental to that.

Does the beta count? Matter of opinion I guess, but I have been using Firefox 4 for so long that I have trouble remembering what Firefox 3.5 (or 3.6 now I suppose) does or does not support.

In a discussion about what kind of "support" WebM is getting relative to H.264, it seems entirely correct to raise that a browser of Firefox's stature is committed to WebM and ideologically opposed to H.264. This fact will not be a trivial consideration when content providers choose video formats in the future.

In a lot of ways, we seem to be entering a game of chicken with IE and iOS on one side and Firefox and Android on the other.
