Mvvm done right

I attended Microsoft TechDays in Stockholm a couple of days ago and went to a session called "MVVM done right". I must say that I was kind of disappointed since it was just a show on how to set up Caliburn.Micro really. 

This leads me thinking about writing my own article shortly. Perhaps titled "MVVM really done right"! But it might be a little bold to challenge a Windows Phone MVP on the matter.

Any one out there that has a good resource on what MVVM really should look like? Don't point on a framework, give me a real article that explains the architecture instead!
