Opinions are like... well, you know the saying - everyone has one. Thom Hogan, knowledgeable, "guru" or otherwise, is a bit of a whiner, so when he needs to hunt for something to say it's going to be stuff like this. Until I see people practically giving their gear away because they can switch from Nikon fast enough, I could care less about PR problems, real perceived or otherwise.
Sure the D600 had issues, and I believe there were a disproportionate amount of owners here who had them, or at least thought they did, and not one of us, no matter how loud we might have complained, switched or even seriously threatened to. The D610 came out and no one has bitched once except to say, "It's just covering up for the D600". Yeah, so what? It's a great freakin' camera, and they even lowered the price $200. Some D600 owners still have an issue to deal with, but it would seem Nikon is quietly resolving them behind the scenes.
Look, BP had a PR issue, and people are still buying their gas. Let folks like Hogan make all the noise they need to make themselves happy. It got the job done because people are talking about it. But it's just noise on top of noise.
