650d vs 600d in the Studio Scene comparison

I fully agree. I had the rebel xti (400d) before my new t4i (650d) and I can't believe how much better the image quality is (@ higher ISO settings like 1600 for example) as well as the rest of the functionality. I just hope DPReview reshoots the ISO 1600 set (at a minimum) given the importance placed on these reviews. There was a time I thought about going with a 7d since it seemed to be a lateral "up grade" to stay with the rebel series but I have since come to realize that is definately not the case. I sold my xti back to B&H and haven't looked back.
