I saw a video a few minutes back that was listed as being posted 12 hours ago.
I hope that he IS back. He did make a video from inside a building as if it were from a room or hospital bed. I'd imagine being bedridden awhile, he probably lost some weight and muscle so he might appear different. The video I saw, he looks like before so it could be an old video he made but just now released.
The man is a huge asset to the hobby.
