Samsung NX1 does 4K and comes at Photokina!

Back in January Samsung unveiled that a new NX1 flagship camera would come this year (article here). And now Photorumors reports that this camera will shoot 4K video and feature a new 28 Megapixel APS-C sensor.

After the GH4 and Sony A7s this would become the third mirrorless camera shooting 4K. But I think more companies (Canon, Olympus for example) will announce 4K cameras at Photokina.

I am a bit surprised to hear the camera will feature a 28 MP sensor. It would become the highest resolution APS-C camera to date. And unlike the GH4 and A7s such a sensor could show more moiree and issues on 4K videos. Or did Samsung find a way to solve that problem?
