I hear you guys. But I'm a cheapskate and would probably be more likely to want to buy the older model to get the best deal.
I would love to have even better low ISO, but as I feared, the 60D has the same processor, so that wouldn't step things up. The T4i has my attention for that very reason. So maybe I just need to wait for the T5i so I can get a deal on the "old" model?
Plus some other things.
1) The articulating screen looks very useful.
2) I have yearned for a higher burst rate for a long time as well. I thought I would be fine when Timmy quit cross countr, but I still keep hitting my buffer. 3) I can see that extra dial being very handy.
I'm just not sure if any one of those things could justify the price of a new one. Perhaps I'm just getting ready for the T2i to die a natural death. I don't know how to find the number of actuations, but I'm sure mine is very high.
