I asked Tom Bihn CS if there were any new Dyneema options being planned for the Co-Pilot in the future. Here is the response, in case it helps you decide whether to purchase now or wait:
"Currently, there aren't any plans to introduce other Dyneema color combinations for the Co-Pilot within the foreseeable future. Down the road, we'll likely make some changes to the available colors for the Co-Pilot, but it's tough to say for certain when we might do this. The best recommendation I can offer is to keep an eye on the blog and forums for any color updates."
