New Keyboard & Trackpad 2 dock

Does anyone know if there are any third party docks/cradles which house the new Magic Keyboard 2 and Magic Trackpad 2?

I have the Henge Docks Clique dock I use for the previous versions of the keyboard and trackpad and hope there is or will be one for the new peripherals.

I understand that in order for Bluetooth to work with the new accessories, I have to upgrade to El Capitan? I'm on Yosemite at the minute.
