5D Mark III
Reports that a few select photographers in Australia have been testing prototypes of the replacement to the 5D Mark II. Australia is used a lot as a testing ground by the sounds of it. Any replacement that comes will definitely arrive in Q4 of 2011 at the earliest.
A couple of folks have mentioned that Canon's recent manufacturing woes could delay some products in 2011.
1D Mark IVn
I received another interesting “rumor” that a replacement to the 1D Mark IV may in fact be a model without video and introduced in 2011. There have been a lot off issues in regards to the rights of still photographers being able to shoot video at stadium events. This is the first time I've heard such a thing.
This is the second time I've heard of a 1D Mark IV replacement coming in 2011.
1Ds Mark IV
Nothing worth writing about has been brought to my attention. The last I had heard, their was going to be a big departure in the model and we may not see it until 2012.
