Is there a tentative release date for this mount?

I would love to try it out with a Burris Fast Fire XTR. Before I saw the announcement for the DD mount, I was thinking of using a YHM 45 degree offset rail. However, this 30 degree DD mount seems to be ideal.

I really don't like the idea of putting the Micro Red Dot on the rings, to the side or above the primary optic. Mounting on a fore-end rail, closer to the bore axis seems to be better solution.
