Sorry, but the steaming pile of ignorance is yours.
> 1. Almost all serious websites are xhtml compliant.
Um, bullshit? Want to try backing that up with something? A random sampling of cnn.com, google news, apple.com, Facebook, Youtube, and LinkedIn shows they all use HTML5 doctype. And here's a graph showing XHTML's continuous decline as it dies a well deserved death.
> 2. Do you imagine that all the HTML5 support that already exists came from nowhere? It was browser devs implementing the pre-reccomendations for HTML5
No, it was browser devs (WHATWG, as the GP correctly pointed out) ignoring the W3C's strict XHTML idiocy and opting for a saner route.
The WHATWG was formed in response to the slow development of World Wide Web Consortium (W3C) Web standards and W3C's decision to abandon HTML in favor of XML-based technologies.

We got HTML5 despite the W3C, not thanks to them.
