This just in!
It will be arriving in Canada by end of the year 2007, so Canadians will now be able to enjoy downloadable TV shows and movies, including a good selection of HDTV content. My source was right that it would arrive soon.
In any case, the announcement is made even more important by the face that Apple’s iTunes Store, which has been around for much longer than XBox Live Video Marketplace, does not yet offer downloadable TV shows and movie episodes in Canada.
