Another Canadian device received the update. But it's not the 920 and it's not Rogers. The Lumia Black update was released for the TELUS Lumia 625 on Thursday.
If it takes much longer we may get Windows 8.1 first. I think that is due to be released in April.
I downloaded the update after I saw your message (I own a Nokia 920).
It seems like this update has been discussed for the longest time. Now that it's finally here, the changes seem minimal.
The new features seem to work well though and the update didn't take long at all.
