New Canon 5D Mark III Rumorations

How about some new juice on the Canon 5D Mark III?  Keith over at Northlight posted some interesting things he heard on the 5D Mark III, stating:

[T]he 5D2 replacement will be aimed at ‘cleaning up’ in the DSLR video market, complementing the video specific 1 series mentioned at the recent Hollywood announcement. It was also suggested that it would not be any more than 18MP, and that any higher MP camera was ‘quite some time off’.

He added that he thinks it will still be a few months before the camera is announced.
Given that the new 1D X is an 18MP full frame camera, it would make sense to expect a similar, if not the same, sensor in the 5D Mark III, along with a less ambitious AF system and frame rate capture.  I’m thinking that we might hear something more about the 5D Mark III and the new “in development” 4K Cinema DSLR prior to (or at) NAB 2012 – not that Canon won’t have plenty to show off then anyway . . . .
