NikonRumors is reporting that Nikon will soon replace its entry-level D3100 DSLR, seemingly corroborated by the recent appearance of "Nikon D3200 for Dummies" guide books on Amazon. The D3200 is said to bump the sensor from 14 to 24 megapixels — if true, the sensor is probably the same Sony chip found in the NEX-7, A77, and A65, similar to how the D7000 and NEX-5n share a Sony sensor. The leaked specs also say that you'll be able to capture four frames a second, one more than the D3100, and there are apparently unspecified improvements to video functionality along with a native ISO range of 100 to 6400.

Maybe most unusually for a DSLR, the D3200 is set to offer Wi-Fi connectivity. We're starting to see Wi-Fi become more of a standard feature on point-and-shoots from the likes of Canon, but we've long wanted the ability to conveniently upload shots from more capable cameras. That said, it could be more in line with the Nikon D4's equally cool remote control functionality. All in all the D3200 sounds like an intriguing upgrade to a fairly unspectacular camera, so we hope to hear more soon — NikonRumors says to expect the announcement sometime next month.
