Are case colors the ONLY change in AW post 9/9?

[WolfSnap]

I purchased a AWS SG on Sept 1, 2015, and am still within my return window... Apart from colors and bands, were there any tweaks to the hardware in the newest watches? Is it worth returning and buying again to get the newer version, if any?

Obviously I don't want to have an old model when I just purchased the watch.....

No change whatsoever aside from gold and rose gold bodies and new colour sport bands and the classic buckle changed. The watch is only 5 months old. There is still lots of time before any actual watch changes happen.
