Not sure if it indicates any change in Canon's product distribution, but during the release of the new TS-E lenses it appeared that initial availability was better in Europe, Asia (China) and Canada than in the US. While it took about 5 weeks for my TS-E 17 to arrive at the end of July, I'm pretty sure I got one earlier than many in the US who placed orders with the larger online vendors. Meanwhile I purchased it through my local dealer (in Canada). I wonder if the priority the US market receives in product allocation during a new product launch has changed, though it's only a hunch.
In fact, going as far back as the original 1D, which was in very high initial demand, I got mine through the same local dealer much earlier than many others on the forums I followed at that time. Since then I have subscribed to the notion that there is an advantage to dealing with a smaller vendor rather than being deep in the waiting list at one of the big online stores.
