Also, I can assure you based on first-hand knowledge, Canon Japan was majorly pissed at the leak of the spec sheet. Majorly!
Finally, Canon is one of the most "Japanese" of the camera makers. All significant decisions are made in Tokyo.
By the way, I worked as both a national Product Manager and a Marketing Manager for a major Japanese electronics firm for 6 years. To my knowledge the only one of the companies in the photographic business that prvides any "real" autonomy to their national branches is Epson.
