Looking forward to buy this baby so much, belive me I wanted this damn thing since I ever looked at the NX1 I almost did not even buy it because Metabones did not have any adapters for it but the specs pushed me.
I honestly never seen a camera system receive so much community support as the NX1 imao. 
Those greedy peckers at Samsung ought to see how much people love their cameras and stop making their damn Galaxy S-infinitiv and make more Smart cameras, Samsung should have made an adapter themselves, I do not understand the reasoning not to, if they did more people would have bought the damn thing. 
Seems counter-productive to me to relay on third party manufacturers to do it for you

Just try to google it http://petapixel.com/2013/01/14/metabones-announces-revolutionary-adaptor-makes-ff-lenses-faster-and-wider/ 
It is similar to your EF to NX adapter but there is optical element that change crop factor from x1.5 to (I believe) x1.1, and you got more light to sensor and shallower depth of field. There is no electronics to control aperture now. Communication between lens and body is different story/project...

I CAN DO IT!
