My XT has autofocus as well. How would the autofocus on the new models differ from that of an nine eyar old XT?

Primarily gains in accuracy, speed, consistency, tracking, AF points, low light acquisition, and the like.

Plus the ability to use Live View, with a touchscreen (and/or an articulating LCD).

With the 70D you gain Video autofocus that doesn't hunt, and is completely silent with most STM lenses.  It's truly a wonder to behold.

Additionally the 70D doubles its AF sampling rate when shooting macros.  Finally making autofocus a (viable) reality for us macro shooters...

"Crazy" bee on a hot sunny day.  70D with 100L Macro using autofocus.   Click on "Original size"

Other difficult subjects become much easier to capture as well...

BIF against water.  100% crop.  Click on "Original size"

And more pedestrian subjects are just a breeze...

Very accurate and consistent AF.  Full-sized image @ ISO 800 (no post processing).  Click on "Original size"

I like to use a single AF point with AI Servo engaged (100% of the time, for all subjects).  Back-button focus is enabled, and autofocus is disassociated from the shutter button.  I find AF to be very fast, consistent, and extremely versatile when implemented this way.

Best of luck,
