PhotographyBlog posted a review of the Nikon D40x digital SLR camera.

Quote from the review: "Announced just four months after its predecessor, the Nikon D40x DSLR camera is virtually identical to the D40, except for one important factor - it has a 10.2 megapixel senor taken directly from the D80, rather than the 6 megapixels that the D40 offered. The sensor change means that the ISO range now starts at ISO 100, going all the way up to ISO 3200. The D40x also borrows the shutter mechanism from the more expensive D80, which results in a slightly faster continuous shooting speed of 3fsp (2.5fps on the older D40), but also a slower flash sync speed (1/200 on the D40x, 1/500 on the D40).
Other than those fairly minor changes, the D40x is to all intents and purposes a 10 megapixel D40, but those extra megapixels mean a higher price-tag, and importantly it now competes with the Canon Digital Rebel XTi / 400D and the Sony Alpha A100."
