Where is Patrick MacRitchie

We are looking for Patrick. We agreed to send him the C3 once it is released, but now we could not get any feedback even many messages have been sent to him. He made videos for C1, and new presentation for C3, He is skilled and the videos are very impressive, below is my most favorite one, it is easy and pleasant to watch. I hope he can see this blog and reach us soon, maybe, who knows?
