Samsung needs people like me to be happy. I know that sounds wildly egotistical and it might be.
But I host photowalks, I go on photowalks. I'm a walking advertisement. The issue is people have heard from me the same thing for 2 years... I love the camera it's great.. when it isn't locking up.. or I get asked did you get that shot.. and I say no I had to take the battery out... or they say hey this group is looking for someone to shoot their event and I have to say "well so and so would be great, I don't have the right lens because Samsung doesn't make it"
If I can pick up a NX30, and I can say, I got that shot, or the WiFi is working great, I love this lens, ya I'd love to shoot that... hey check this out, it's so handy. The System is really maturing. It is good for Samsung.
People are always fascinated until they see me curse the NX20
So honestly the NX30 needs to be the Camera. It's got to be on par with the D7100 and 70D in all but it's Weather Sealing
it really needs to that level. I think it if it lives up to it's spec's it may just do it, and might actually over take it. If you combine that with lens' coming out.. well that will help entice people and if NX users can then show that the camera can do all and offer a travel body with the same mount like the NX2000 that could be the tipping point.
And that is what they need to do they need to try to entice Crop shooters to the NX system. More and more the Crop Sensor is fully capable of work previous held by Full Frame if only because of the Low light performance.
Samsung isn't missing much at this point if the NX30 lives up to the theory and stats that has been shown.
