I'm that fag who ripped/storytimed the Shadow manga and the first chapter of Blade of Courage. I've ripped some design notes about Shadow Generations and Movie 3, it has some interesting internal information about how the staff communicate and what programs they use for animation and rigging. For example, Jeff Fowler and co. apparently did video calls with SoJ.
I'll translate it all, but only if there's really interest, since it takes effort.
