According to Amateur Photographer Samsung's likely out of the DSLR business:

Samsung GX. No real prospect of comeback news - Amateur Photographer - news, camera reviews, lens reviews, camera equipment guides, photography courses, competitions, photography forums

When asked how the NX range would develop Park said that the company obviously intends to produce more bodies in different forms and of different sensor resolutions, and that some models would appeal to professional users.

Professional users? What does that mean - FF EVIL or what?

Well, Samsung could use its GX system and become it in EVIL FF system.
Samsung could use the K mount and keep the flange distance or a new FF mount and a shorter flange distance.
A new completely electronic system.
