Lots of full frame cameras coming out and Canon gives us firmware updates and a white Rebel. That's pathetic.
Respectfully, for all the hurt feelings with Canon not pushing the performance needle every year, this is the industry standard to some extent. See the graphic from http://www.northlight-images.co.uk/rumours.html that I've attached.
New FF rigs come every four years or so and Rebels come every year. The only thing that screams refresh in that timeline is the 7D.
And Nikon's not that different, btw. Their timeline is also on that page for review.
It's Sony that's really winding people up with frantic development and commercialization of FF rigs. But with each one (the two RX1 rigs and the two A7 rigs), they look interesting on paper but have a serious drawback once a veteran photog gets to play with it. I honestly trust Canon (and to some extent Nikon) to take forever on the new tech to make sure it works for folks like us, Nikon D600 dust notwithstanding.
