I was surprised no wifi, as that's pretty standard now. There are a lot of applications where wifi can really help out, especially if you want to fire remotely, the Canon 6D setup with Canon app for the apple or android OS is very nice indeed.
LV improved, would sure be nice, it will be interesting to see just what "improved" means, maybe not allowing the focus at 100% to be worthless? at least to me, where I always back off 3 to really use it. There won't be focus peaking without a EVF as far as I understand it.
Sony has a lot of the answers out there, but as an owner of a lot of Nikon glass, I don't want to use it in Manual only (A7r) and Sony refuses to create/make/license a true intervalometer. Their timelaspe app, is tied to the 30 seconds max of the shutter, you can't use it in bulb mode. For creation of a timelape video, 30 seconds is Ok, but for stacking for night photography, 30 seconds will rarely fit the shooting scenario.
I like the new base iso of 64, and a bit faster frame rate with the grip. The sRaw is not like Canon's in that it appears you don't keep all the raw info, it's more of an abridged file, almost like a jpg.
Early reviews should be out soon, as it will interesting to see what the the initial impressions are.
