This is going to be an interesting development, depending on how much access to the camera app developers will have, this could be huge!
Am I interested in it? No, ergonomics don't look great in that you will have to use the LCD to change most settings since there is 1 dial & maybe 3 buttons, plus the M mount lens issues, and its a bigger camera than I'm looking for right now, and I do have my heart set on a FF as my next camera.
More interesting if Cyanogenmod supports it so we can ditch Samsung's buggy, slow and lousy TouchWiz UI for Android.
That said, looks more than a little interesting. This is exactly what Samsung needs to be doing with the NX line to make it interesting. Oh, and it better have an SD card slot.
