When you review a camera, its for performance only, since critical information such as reliability is not available. They do not take into account support, or availability of accessories.
Those things are important to professionals, but not necessarily to comsumers, not at least until they need support before a upcoming vacation, or they try to find a accessory that they assumed would be available.
Apparently, DPR did not find the overheating issue, many others have not been able to find it either.
Sony is making progress towards becoming a mainstream professional provider of cameras, they already do very well with video.
I've had various Sony products, starting in 1966 when I bought a reel to reel Sony deck. It failed far too early. I've owned Sony High End Stereo receivers, various point and shoot cameras, personal cassette players, personal CD players, bought my son a playstation, every one failed early on. At this point, I avoid Sony like the plague, even if they produce reliable cameras, I'm pretty immune to the hype.
