RE: YS115FZ-S when/where available??
You might call yspartsandservice.com @ 775 267-9252. They told me end of the year for the 1.15. I would imagine they have seen one by now though and could probably answer your questions about the size of the case. If would be my guess that the exterior of the case hasn't changed from the 1.10S.
