Any update about D5100 successor?

Even if the D5200 would appear the day after you buy the D5100 that doesn't mean that the D5100 can go in the trash bin.

The D5100 is a very good camera and will still be no matter what the successor will look like. And with the current price you can't go wrong with it.
