My dealer informed me this morning that Canon is shipping their 5D order "in a day or two" and they'll ship my order this week.
That would be nice, means that we soon can expect real live samples 
Let's all keep in mind how the world of retail works... if March 22nd is the "street date", stores will be getting the product a few days in advance to prepare inventory, assign SKUs, etc., and to educate salespeople on the new features of the product.
My local shop informed me that they were told to expect delivery of their 5D3 stock early next week, although contractually they are obligated not to display or sell any 5D3 bodies prior to the 22nd. I was told this the day after launch (March 3rd), so things may have changed in the last week.
If not, the 22nd will be the first day we see hard product.
