Assuming that your hypothesis is correct, that would be putting the next FE on Holodeck some one to two months after the F2P relaunch. I dunno about anyone else, but that's a bit of a kick to the teeth, IMO. :/
I'm simply saying I think they want to have it ready BY then. That doesnt necessarily mean they are going to wait UNTIL then do release it.
The last word on the new FE was that they wanted to get the Game Event system into place to handle the scheduling of the new FE series rollout. Right now they have to have someone in ops has to manually kickoff the new FE missions when they go live.
