My thoughts are these ideas will take longer than Gorn appearance revamp to go live.
So 2013 might be a good time to start a Klingon?
Depends... If it needs new maps and the map experts are booked solid, then it'll probably wait. If it needs new objects to put on a map, likewise. But since these would be based off of existing missions, I'd bet that the requirements would be reasonably modest. I wouldn't be surprised if a good Foundry author would be able to make one, given the right maps and such.
I'm thinking Gozer could whip up new missions pretty darn fast if he gets enough breathing room. The key to making them successful is a good story hook that doesn't make the missions feel like retreads.
Yes I see there still not in teaching even though we told about these mission back in march. In that time federation got three remaster episodes. I would not expect those mission till September at the earliest.
Of course we also told we getting a klingon academy. Starfleet gets there tomorrow and as normal nothing for the Klingons.
