They're going to try to get a F2P Public (well Public as in Subscribers) test server, possibly replacing tribble by the end of this month/early October.
They will be Premiering the DOFF System and the Next feature episodes series on there, along with the new economy system.
The new episodes series will be sometime in October on that F2P Test Server, and will be on the live server by the time F2P launches officially near the end of the year.
I heard all of this on a live interview with Dan Stahl on a podcast, which will be on there show next Tuseday if you want the full scoop.
Also the Enterprise-F class will not be on the Microtrans Store AT ALL, It will be earned ingame in a future mission series,, weather it be a Fleet event or what is not known.
