There are many other lenses that work well on the D800 and D800e and many more than that if you are pragmatic about your choices. Not everything in life needs to be absolutely perfect, and that was the case prior to the D800, too. I personally believe that Nikon put that language out there (the 16 lenses) as a defense against obsessive photographers who would go nuts viewing their shots at 100%. It was also a bit of a marketing tool.
If a particular lens of focal length range is extremely important to you and you plan to make really large prints that absolutely need to be pinpoint sharp, by all means spend the money for those lenses. If it's a range that's a bit less important, and you don't plan on making 24x36 inch prints, you can relax a little. If you come to the correct realization that no one else actually cares about the sharpness of your photos in the way most photographers do, you can really relax. On the other hand, it may make you realize that ideas, composition and light are what they're really paying attention to. The D800/e is a great camera with any lens. There's more to it than just pixels, especially given how few photographers print their images these days.
