Some news would be good, after all N3V are in a good position to trounce the competition. MSTS is all but obsolete, Railworks is all about payware, Zusi 3 is still vapourware IMHO and the new Run 8, while showing promise, seems mainly aimed at multiplayer use.
A TS13, incorporating a few of the suggestions made over the years, could run rings round the above.
Sadly, given the almost complete lack of response by N3V staff or managers to ideas in the Suggestion Boxcar or other threads, one has to ask is there actually anything else planned for the PC end of the franchise? It wouldn't hurt to pre-announce a new version in the works, wouldn't necessarily hurt sales of the existing versions as many people prefer to buy and use these for their own reasons.
