It would be nice if Canon had/stuck to a naming convention like...
1D thru 5D = full frame "pro" model
6D thru 9D = crop frame "pro - semi-pro"
10D thru 90D = crop
100D thru 2000D = entry level
This is how it looks now anyway, so if the 3D is a crop sensor, you can chuck this nomenclature out the window.
