It will only change if:
1) patents expire (which will take too long)
2) we do something about it (or at least attempt to).

Have the requirements of all the companies been collected somewhere?  If 
not, we should do so.  What are Apple's requirements?  Maybe the thing 
we can change is those requirements.

Well, there's usually a short-term winner, or companies would simply 
cooperate.  I don't think we should reward such behavior.

The best way to avoid a format war is to find a video codec that can be 
mandated in the HTML5 spec, not to avoid the issue until it's too late.
