Nikon has officially discontinued its D700 and D300s cameras, listing them as such on its Japanese website. Speculation has been ramping up over the mythical D800 full-frame 36 megapixel DSLR, and the discontinuation of the predecessor D700 will only fuel that fire. The D300s cancellation is also interesting, as we haven't heard much in the way of rumor surrounding a potential prosumer successor from Nikon with an APS-C sized sensor. We might not have to wait too long for official confirmation — if either camera were to be announced, the CP+ show in Yokohama in a couple of weeks would be a pretty good place to do so.
