Looks like a confirmed no hot-shoe mount. Don't think this is wise because it negates buyers from even considering buying a speedlight from Canon. I infrequently use the SX50 with a 600EX-RT because the onboard flash just doesn't have enough flexibility. My $150.00 refurbished SX50 is looking even more worthwhile keeping and not upgrading.
At this rate, they will remove the shutter button to save money on the next round
