for those who haven't seen the CBC/Radio-Canada opening, here it is
I always love the CBC Opening not only for the theme music but also for the the subtle respect for the host nation. There is no doubt where these games are and past games openings have had writing and symbols in Japanese, Chinese, Greek, Italian and now Russian. You'd have to watch it many times to catch all the background text behind the graphics
And they can play this theme many different ways unlike I Believe which was pretty generic.
