Sony and Panasonic developed AVCHD. Sony did Blu-Ray. 1080p60 is related to both those standards. Apple, Microsoft and Canon were not on the AVCHD bandwagon. Further, AVCHD 1.0 didn't include 1080p60. And AVCHD 2.0 came out a year ago and included 1080p60. Again, it was Sony and Panasonic in charge. Further, Canon does not make Blu-Ray players or TVs so the 1080p60 and AVCHD formats are not important to them.
In summary, if I buy a Panasonic Blu-Ray Player, TV and video camera the harmony of AVCHD is there. I can take a video, pull the SD card from the camera, put it into the TV or BD Player directly and watch movies with a menu. Same with Sony. My Sony TV responds to my Sony camera and reprograms itself the moment I connect the two with a cord. The TV remote will run the camera slide show.
Canon would have to fall on its sword, to promote that kind of unity with TVs from Sony, Panasonic or Samsung.
I'm not completely sure I have the details 100% correct, but I think I'm close.
