You are right -- I actually did go ahead and email and got a quick response:

"Thanks for reaching out and for your interest in Cannondale. Although the CAAD12 will not be offered in a women's specific design for 2016, the 2016 women's CAAD10 full specifications should be available on our website in the coming days."

I'm not sure what this means for my new bike search - I assume prices on the 10 will drop once the CAAD12 WSD is out? (Of course, I also might be one of those suckers who springs for the new fancy shiny thing).
