I was pointing out that AVCHD may not be the best choice, since it is highly compressed, and it is hardly a breakthrough to do 1080/60p AVCHD. Also, bit rate is everything in video quality.
I wasn't commenting on DSLR v camcorder, but Sony v Canon.
But, since you bring it up, while DSLR video does have advantages from the large sensor DOF, lens selections, etc. HD video itself is actually quite low resolution so you may not get as much from that sensor as you are expecting.
If they'd announced 4K video, then that would be something to crow about. 1080/60p AVCHD? Not so much.
