I'm really quite old school, I only change when my existing kit fails to do what I need it to.
To give my Pentax brand example, I went from K20Ds straight to K1s, as they offered the FF that I had waited for Pentax to offer.
Up until then the K20D's still provided for my needs, all right with some obvious limitations for sure. But I'm one to work the problem to resolve the issues with kit I have in hand, not to find excuses to not get the results.
That's probably just as well as I'd be out of job, if you don't bring back the images your sent out or commissioned to do.
