Well ... they recently said, that they're able to make only 10-15 Story Missions a year .... considering they still have to work on the KDF ... you can guess how long it might take them to make another complete faction with at least 10-20 Missions ....
Cuz that would make my year.
not this one .... or next ...
by the way things seem to be going right now .... not before real Romulans visit Earth, to bring us Story-Mission-Replicators
Not on the list, neither seems to be adding the other half of the Klingon faction levelwise.
Well they've told they're trying to work on this 2012 ... even IF it would only postpone a possible Romulan Faction
