Photorumors just now. The long rumored 15mm super wide is finally coming to SLR, reportedly coming on the 16th of March in ZF.2 and ZE mounts. The ZM Distagon 15/2.8 is the only current 15mm by Zeiss, and it is made in Germany, costing $4,600. The SLR version though should be made in Japan, and costs a lot less.
