It's only a matter of time until Canon follows through on this. Like they did with the 7d sensor, they'll place a full frame sensor in multiple bodies, stretching their profits from the r&d and actually reducing costs for the consumer in the long run as well. I wouldn't be surprised, given that the 5d mark ii is fairly frequently backordered, if Canon simply placed the same sensor in a plastic body, stuck a digic 5 in there, and pulled a bunch of features out. The cost of producing it would not be staggering and i surmise it would sell well as a prosumer camera at around 1600?
