Interesting… It seems to me that the majority of people watching it would be doing so digitally (since it’s a web file). Will he be releasing it in a smaller digital format?
I don’t think they’ll ever be released officially in a smaller format.
What you can do is download the AVCHD version and use Handbrake to convert the m2ts file (ISO\BDMV\STREAM) to mkv.
You can google “optimal handbrake video conversion” for the method I used. It’s the second link. This will compress it to ~3GB at 720p.
