I think that the camera is well spec'd for a first Canon FF mirror less. As far as IBIS goes, sure I would like to see it, but I have heard that IBIS is not as good as IS in a lens. Still, it would be nice to have and I think at some point Canon will include it because most other camera companies will offer it. If the comparison to the 5DIV is correct in size, I like it. I own a 5DIV and like it, but as a travel photographer, I see it as my last DSLR, mainly due to weight with L lenses. It will be interesting to see how the sensor performs. As far as appearance go, I find it much more attractive than Nikon Z7/6 bodies. They are pretty ugly, but a camera is a tool, not a thing to look at or ogle over. It's job is to capture good images and with the new array of mirror less L lenses, I am sure that it will do just that.
