If the release comes from Japan, it will start in Japan, with Japanese content. Tie-ups with B&N would be a good deal for both sides. The Japanese have talked about this for years. One of the first targets would be the newspaper publishers. They have the infrastructure to pull off a wireless distribution channel from the train stations. (curiously this didn't happen with Sony).

But, I could be very wrong, and Taiwan might actually be first mover: http://www.epapercentral.com/pvi-to-mass-produce-ereaders.ht...

If they are though, funnily it would not start in Taiwan with Taiwanese content.
