I'm not a Kirk Tuck fan but I don't have a problem with his write up bar a couple of obvious points.
No photographer event or not is going to set up the camera to display the image in the VF for 2 seconds for one obvious reason. You can't see your next shot or the subject, and missing it isn't an option. If I had image review on and shot a wedding it would be a walking disaster for my type of shooting, I simply don't have time to review images at critical moments, and honestly the lack of an option for "review images only on back LCD" is a very very notable issue I have with the current SLT Models. You just don't have this option and you're basically forced to turn image review off.
Maybe Kirk works in a different way to me but I suspect a great deal of users will be turning instant image review off full stop. Really this needs a look from Sony to fix this annoying quirk. As for the zoom and jpeg, fine if he likes shooting jpeg no problems it's hardly worth shouting about though.
At the end of the day whatever I think or whatever Kirk thinks I honestly do feel that this isn't going to have any impact in the market in any serious way. It might hit the spot for some A mount users. Not to be overly dramatic but I'm seeing landing craft on the beaches..aircraft flying overhead (Nikon), and the The führer is asleep (Sony), and nobody is releasing the Panzer divisions
Nikon are full out on the offensive and Canon will respond too, 2013 will be a very important year for the full frame market.
