Raid, i'm actually looking for updates myself.
He made update 3 public, but it's short.

I forgot to mention the very exciting news that I will be working with Kolari Vision (who do IR conversion for many cameras:
http://kolarivision.com/) to replace the thick sensor stack included in the A7 with a new thin sensor stack. This greatly improves the corners on many wide and even standard length lenses, designed for no sensor stack.

Sounds like he got it working on some level.
