Thanks for the opinions, but I did a little research and found the actual answer (google is amazing). Since they are a german company they are prohibited from making AF for EF and F lenses. All the third party lenses for EF and F are from Japanese companies. It has nothing to do with creating lenses for purists or costs, just international prohibitions. As evidence, here is a quote from zeiss lens team.
"Due to international licences, it is not possible at the moment for companies outside Japan to offer AF lenses with EF- or F - mount. So we will concentrate on high-end manual focus lenses with those mounts within the next future.

They should relocate to Japan for all our sake (pun intended)
I read the same thing. It's not by choice. I still love their lenses, though.
