Anyhow, most would say that T2i, T3i, T4i, 60D and 7D basically have the same sensor.
Yes. I think the newer processor in the T4i makes up for the dual processors in the 7D.
The T4i is a great camera all around. I like it as much as I loved my Canon 1DsII in 2004, at $8,000.
The auto focus for stills is a nice upgrade from the T3i. In my mind, that leaves the T3i DOA for stills. The T4i has the 60D auto focus.
The T4i touch screen LCD, and the auto focus during video with STM, are both nice features. The latter has convinced me to sell my camcorders for events - the T4i creates more files, but the quality is worth it.
It also has some nice features like the hand held high ISO noise reduction (with multiple exposures), etc. that make use of the new processor.
Buy it at a good price, like $600+ for the body, or with the 18-135 is you need that and it won't cost you much to own. T3i's were selling for $550 to $610+ when the T4i came out in June, so the net cost of ownership is like $100 for a year.
I decided to use only the T4i for my work, until I needed high ISO for events and bought a 5DIII for 6400 ISO. But the depreciation on a 5D3 (purchased now in the $2,800 range) is probably about $500 per year, so the incremental cost is pretty big (although well worth it if you need it, and so cheap compared to film.)
