I would say the sales sucked compared to the others. I was considering it this year too, but the colors are rather meh to me. Grey and White rather unappealing to me and after the first Apple Edition that was gold and now totally useless for $17k who would even consider one.
The new AW S4 looks like they built upon the features and added new tech, the ECG will be nice, but I suspect that app will be 2019 and they just don't deliver like they did under Jobs.
