Yes but for completely different reasons. I disagree with you quite a bit. First I think they are covering the High end quite well. The only thing they do not have covered is a high MP studio/landscape camera. But who was even thinking that before the D800. What Canon lacks in IQ it makes up in focus accuracy and ergonomics.
No I am frustrated because I drove off into a ditch and destroyed my 60d not to mention the water damage to my truck. I had to buy a replacement 60d, because there was no new crop sensor. The 6d was released one Month to late. I went to Best Buy 5 days after the Nikon D600 was announced and there was one on display. It seemed to focus with all of the speed of the Nex 3 whatever they had on display. So I was not impressed. I am frustrated by the slowness of Canon's new sensor developments. The phase detection on sensor was promising but there was no real noticeable improvement in auto focus in live-view. So what is the point if there is no improvement in live-view auto focus.
No the real frustration comes from the apparent lack in development of a new crop sensor line. No development of better contrast Auto focus, for live view and P&S use. No real interest in EVF or hybrid viewfinders. As well as the general lack of innovative new products. These lead to the EOS M being a laughing stock compered to the competition. Canon has not really shown any progress on the software side. The current Olympus OM-D can pick the eye you want to focus on, right, left and nearest.
Hopefully in the next couple of months Canon will announce their new sensor tech and it is much improved. The time it is taking is my biggest concern. It looks like it will be a few months before I can afford the 6d, and I really have no trips or events planned so I will wait until Canon announces the new sensor. I hope it is not a long wait. I hope the wait is justifiable instead of like the EOS M witch was such a disappointment I bought a Sony Nex6.
