positioning could very well be a huge factor and Canon may think 1.6 crop is only for families and trips to disneyland, but then why even bother making the 7D? kind of pointless without lenses to match in quality.
I do believe up until maybe 3 years ago Canon probably did believe that the 1.6 crop was a "lesser" camera system and wanted to nudge people up the food chain up to full frame... The EF-S system was catered to the 20D and beyond and were geared for that clientele. I think when the 7D was introduced they realized people who were invested in the EF-s system (and frankly those who weren't going to buy a $2500 camera period) needed something to upgrade to and so the 7D was born... Somehow I almost dont think Canon realized how big of a hit the 7D really was. While I would be supprised to see some L-s versions in the future or some other designation for top of the line ef-s series, that probably wouldn't be introduced until after the 7D2 comes out so there's enough of a saturation in the market of APS-C weathersealed 7d cameras out there to match up with the lenses.
professional only means paid my friend and has no bearing of skill.... with that, I dont get paid but still consider pro equipment a necessity and the 7D to me is the smallest "1D" Cannon makes. Furthermore, if apple engineers can make something like the ipad, is there really a need for the 1D to be as big as it is anymore???
Correct, being a professional photographer means you are a paid or commissioned photographer... I make all my living off of photography and my skill set, however I do not use 1d series cameras... That being said, if I was in the position or need for that type of camera for the style of photography I was shooting or shooting for a client whom this gear was needed, then by all means I would have it in my budget to get one. There are professional photographers can make money whether they are using a 1Ds/x or an iphone... It's all about knowing what equipment you need to get your job done and most importantly knowing how to get the most out of what gear you have to get the job done.
