Thanks for the pictorial comparison. IMO, one of the best features of the body shape, is the solid right hand grip for the Nex's, including the A7 series. It provides a very secure handhold which is not present on the Leica camera by its side. If they provide an improved menu system over the Nex as suggested by the post above, and a few normal to moderate zooms over the next year or so, it'll be an easy winner.
The first time I saw the aps nex body shape, i didn't think it was very attractive, but now that i've used them, I think they look great - but then i've always been a fan of functional designs.
