As a longtime DX user: 2 D200's, a D90, a D300 and D300s as well as the new D7100. . . I'd like to see a D400 . . . however in no way have I ever felt I've " had to settle" for the D7100. I can honestly say I've taken the best photos of my life with the D7100 - and it had nothing to do with the size of the buffer - but everything to do with the quality of the image it produces.
