I'm nearly ready for my next upgrade. The S4 tempts me. My wife has a DNA and it's a great phone. Blows my Razr away on many levels. I'm torn. Wait for the mystery Moto X, or jump over to an S4? My battery is sucking eggs on the Razr. Beyond that, I have loved my phone over the last 1.5 years. (almost). Moto sells me on the build quality, but I'm not sure I can take the constant charging on my phone much longer. I manage a tree cutting service for a living. I need a good, reliable, TOUGH phone. Not so sure the S4 will live up to the tough part.
