I was waiting "for something better to come out" when I bought the D5100 in June, 2011. Now, in November, they do have the new cameras with a prime lens. These are better, for some people. It all depends on how serious you are about photography and your best use. I use the D5100 for making professional photographs in a variety of settings: outdoor, studio, weddings, classroom. It is a great camera; just not the best one. Consider it a mid-range machine, but an excellent one. I know a professional photographer that uses his "best" cameras for photographs but uses the D5100 exclusively for taking video.
