You'd think that a camera company would actually like to sell cameras. But if my experience in trying to get a GH2 is any example, Panasonic doesn't think so. Amazon ended up cancelling my pre-order. My local dealers are having troubles getting any GH2s from the Panasonic distribution channels in the US. My favorite dealer tells me that he has no idea if he'll get even one, and when. (Several people have written me about trying to get a GH2 from Panasonic's own Web site in the US and having their orders dropped or not fulfilled.)
This isn't the first time Panasonic has had trouble getting product out in the US in a timely fashion and meeting demand. The GH1 and GF1 both went through similar problems. By the time Panasonic managed to get sufficient supply into the states and distributed into the sales channels, they had to discount the product to sell it.
Nikon and Canon would be in a lot more trouble if the other camera companies actually were better at predicting demand and filling it. The current situation won't stay the same forever. You have to think that a big brand like Panasonic will eventually figure out how to sell in the US.
