This is the sad state of what used to be our passion, Photography used to be an artform for expressing and sharing our feelings, emotions and observations. Today it has become, "I've got the latest and greatest, who cares if I don't know how to use it". Who cares if I never create an image or take a photograph that will some how impact the viewer. All I need is a lot of MPs and FF and I am happy.
Just get over it and get into why you wanted a camera in the first place. I could continue to make my living with what ever camera brand I choose and I promise you none of my clients will ever ask me whether I use Canon or Nikon.
I'm sure the guys and Canon keep updating because of their love for customers like you. They know every thing you buy is disposable. Next year what ever you buy this year will be updated and you will again have to have the "Latest and Greatest".
