My thoughts exactly. I'd say the over/under of the next time we see the question "Will my flight on 777 going to have the new C and F class seats" at one month, maybe less.

Uh, I don't think you did. I'd hazard a good bet that there isn't a 767 out there than can do YVR-SYD nonstop (or at least do it with people and/or cargo). AC has been using the 777 on the YVR-SYD route since it's inception.
