Neat news! Apparently the series is growing hard and well.
I would love for it if ZUN took some pointers from western indie studios and offer download versions for purchase, but it's understandable that he just keeps with a few burned copies on discs distributed in a few venues only. Even if he doesn't do that it would be really nice for him to arrange deals with others to burn and sell the discs, especially in the market outside Japan...I will attribute his not doing either to artistic vs. monetary intent (understandable) and smug Japanese island syndrome </nationalism>.
