Chances of a fast wide prime?

I am very excited about this:   http://www.metabones.com/images/meta...te%20Paper.pdf  I did reach out to Metabones today and they said the Micro 4/3 version will be out soon this will allow us to use FF wide lenses at their actual focal lengths on Micro 4/3's cameras.  If the image quality is good I will get one of these.
