I don't get the rationale of changing the hotshoe design either. The old Minolta one didn't strike me as being very sturdy (I was a Minolta user sometime in the past) but why give up on it? The Canon and Nikon flashguns won't work anyways, and putting a 50 year old "dumb" flashgun on a DSLR is at best debatable, and at worst might lead to fried camera.
At least I hope there's going to be a small adapter so that the existing flash owners aren't completely screwed over. But that's introducing another vulnerable joint in the system.
