No one is quite sure. There is speculation that a new game is about to come out, but I don't think that likely.
From what I've been told, Paramount has been going on a C&D binge since sometime around May with anything Trek related it can get it's hands on. Scans of the published material were always copyright violations in the legal sense, but up till now they were semi-tolerated by the rights holders for just the reasons you gave above.
That is no longer the case. Paramount is exercising it's rights as IP holder on Trek and cracking down on anything that infringes it's property.
The open question now is whether or not they will branch out even further and start going after things like fanfic/fanfilms and independent artwork based on Trek.
