Looking at release dates I would say that it is likely they may release a 400 in Jan 2014.
They have two series of NX cameras (100 and 1000).
The 300 was released in Jan of 2013.
The current trend is to release a new model of popular cameras every year.
You can make your own guess from this:

Ok so will be buying a new camera in feb 2014, and ive decided on a samsung nx300.
Question, is it likely to be replaced by samsung with a newer or updated camera in the next 6 months? If so I could probably wait. Dont want to buy one then find out a newer/better camera is available a month later!
