A couple of days ago I received an email from Geert van Horrik, a developer working on a new MVVM Framework called Catel. Geert asked me to update my MVVM Framework Explorer app in order to include his new framework. Here is the resulting updated app (click to launch):

Besides adding this new framework, I updated the download count for each framework, which allowed me to do some statistics. Here are the download progression for the most popular MVVM frameworks between July 2010 and January 2011:
