I received the following response from Hiroshi at Jitensha Studio regarding cost and availability of the Sugino crank:
"Dear Mr. Charlie Young
Unfortunately I don't have a any idea right now. If I will get information from Japan, I will put on my web site. Thank you very much.
Sincerely Hiroshi"
I guess the best course of action for those of us interested is to keep a
collective eye on the website http://www.jitensha.com/
Thanks,
Charlie "collective eye?" Young
