Wow. I found a pretty neat video shared by @chinaavreview that details the construction, painting, and rollout of 1499. Looks like an official Boeing video, but I don't see it yet over on the 747 website.
I'm guessing it will end up there eventually. Tangentially, it looks like the "Who's Flying" section has been updated to show Transaero as well. Interestingly, it still lists Arik Air as well.
