There is a Nikon D300s DSLR coming up?
Photography Bay points out a screenshot taken from a Nikon USA website, showing an LCD capture with the name Nikon D300S. There's a couple of other observations made on the picture, which has a medium-size picture capture, so it does not reveal the "megapixelation", although some could speculate based on the "M" size.
As you may recall, Nikon has been fairly consistent in its use of postfixes in model names. Names such as "X" (eg D3X (vs D3), D1X (vs D1), D40X (vs D40)), and "H" (eg D2H, D1H), and "S" (eg D70s (vs D70)).
So if the "S" is any indicator, we should expect a D70-to-D70s type of a transition, which could mean, 12-megapixels. But what about DSLR-Video?
