OK...gotta say...Camera Canada's website does not surf very well or give clear information. On the 24-70mm f/2.8II page..it just doesn't say if its a pre-order or anything. (also...the only way I could get to the len's page was thru the link here...I went to the site and tried to do a search...60 pages come up in the search for the lens...starting with point and shoot cameras (yes..I tried to search every which way)....then if you try to go to the Canon lens section...the choices are "tele-zooms", "wide-angle-zooms" "Normal primes"etc..

??...no kit zooms or normal zooms or anything like that?

?? It is as if someone who knew nothing about photographer's needs put their search categories together? Go figure....
Anyway..... the 5D III body-only says "in stock"...that little ditty is not listed on the new zoom lens page (the page says nothing other than the lens is on sale.......so I think it is a pretty safe bet that they DO NOT have the lens a week early....especially with the delay rumor.
I sent them an email to ask...just in case.
Hope that helps.
I really want that lens, too....I sold my 24-105mm to buy it..and now I am standing here with my pants down!!! LOL! ....oh well.
