Focusing is the only important factor in modern cameras - and the one that manufacturers other than Canon and Nikon can't get right (and Canon still manages to screw things up).
The problem with manual focus - even with focus peaking - is that a lens designed for autofocus has a much shorter distance the focusing ring has to be turned than a lens designed for manual focusing.
So we'll see whether it's a great camera - or just a great sensor in a worthless body.
Image specs are always great. The only thing that is important is how well it focuses.
