Because its a custom regulation in europe and other countries. "video" cameras get an extra Tax which is substantial. Most photographers dont want to pay 20% for a camera, just for a feature that 98% of people never miss. Thats why nearly all dslr/dslm cameras are limited to 29:59I wish he'd asked why the 29'59" record limit is still in place!
He would have made a fool of himself if he actualy ask such a basic question to a canon exec.
