ignore top tube and head tube, they don't mean anything.
stack and reach are what you want to look at, and yes the only substantive change on the S5 is a small reduction in stack, as this was the primary complaint about the geometry. However your old S5 stack/reach numbers don't look right.

I have a 2014 S5 VWD, which replaced my 2013 S5 Team. I sized down from a 58cm to 56cm frame in order to get my front end low enough.
On the 2014 S5, I run a -17 140mm stem in order to get the bars in the right place. Stem choice is not great in that size, but I only run a single 1cm spacer underneath the stem, so the tall headtube of the 2013 S5 dictates that I size down and run the long stem.
I've tried to remain disciplined and not entertain the prospect of a frame upgrade, but just for fun I decided to check out the updated frame geometry. I've read the reviews discussing how the overly tall head tubes were shortened for the 2015 version. But the geometry doesn't all that different:
56cm:
- OLD: 565mm top tube; 160mm head tube; 560mm stack; 394mm reach
- NEW: 565mm top tube; 157mm head tube; 565mm stack; 392mm reach
58cm:
- OLD: 580mm top tube; 180mm head tube; 580mm stack; 403mm reach
- NEW: 581mm top tube; 181mm head tube; 588mm stack; 401mm reach
So lemme get this straight, the top tube on 58cm size of the new S5 has been INCREASED by 1mm?
Comparing the measurements of the old and new frames, I am not seeing much difference. The biggest single difference is 8mm of stack on the 58cm frame, but even with that frame, each of the other frame measurements is within 2mm of the old frame. It's a similar story with the 56cm frame, no measurement varies by more than 5mm.
