Prompted by the blog post in the title I read most posts tagged "5d-mark-ii" and just bought the camera. The Mad Max post from September 2014 hinted at a potential guide for the Mark II as well "Keep an eye out for the updated guides soon on EOSHD" (but the link was to the Mark III raw shooter's guide).
@Andrew Reid: Is there going to be an update to the Mark III guide that would include the differences from Mark II? Or maybe a standalone Mark II guide, whatever you think makes most sense? Or would you say that Mark III guide could be used by Mark II shooters too, with virtually no significant differences?
