I just watched this video and it's becoming more and more clear that the Klingons are destined to remain the Red-Headed Stepchild of the Federation in game.
Feds get more playable races, new ships, off-duty clothing . . . we get some lame looking ship customizations for existing ships? Add this to the really awesome randomly generated content that's apparently going to pass for Klingon PvE, and I wonder if my Brigadier General is going to continue to collect dust.
Now I hear that they're working on another new faction, and it's clear, Klinks are going to remain in their current form. I'm sure Cryptic is determined not to make the same mistake they made with the Klingons with the new faction, and will devote sufficient resources to flesh them out, thus the Klingons will remain forgotten.
