The current HTML5 spec has severe breakages from IE's implementation already.  (E.g. removing the classid and codebase attributes from <object>.)  This is why I needed to write up my thoughts.

And saying that the DOCTYPE is <!DOCTYPE html5> rather than <!DOCTYPE html> doesn't say that the next version actually needs to be HTML6, or that it will necessitate a new DOCTYPE version.

They are both part of the story.  My essay will go out later this morning.
