I think all the 1 disc DVD has as far as special features go is the audio commentary, but I may be wrong about that.
I'm getting the Blu-Ray version with the 4 pins. I'm still surprised that they made a "medical" one since we have never seen that. Heck, I don't even remember seeing the "medical" insignia even in TOS.
And yeah, the Vessel Simulator on the Blu-Ray has only the Enterprise and the Narada. Which is fine, I really only want a closer look at the Big E anyways.
