Should I get the Canon 650D once it comes out?

I'm still happy with my 550D. The 600D had the same sensor, so there didn't seem to be good reason to buy it. I'll wait and see if the 650D is a big improvement. There will be another one next year, don't see much point in paying just for a higher number, they have to make a big improvement or I'll wait until my shutter breaks.

Skipping the latest model saves a lot of money over the years, I can waste that on lenses:)
