The plot thickens... (dramatic pause) dum dum duuummmm...
But seriously, I have no doubt that the IQ will be acceptable; I, and I'm sure many others, are more concerned about the AF. I fully understand that this is a compromise camera, spec'd and priced for a certain bracket in their lineup; but I'd be very disappointed if the AF performance is less than the 60D. I know spec wise, it looks to be lesser, but it could still perform better, especially in low light with the -3EV sensitivity.
I really want to be able to like this camera so I can get it plus a decent lens, instead of having just a 5DIII and having to make due with my current mediocre glass.
