Yes, I'm going to use SG-A as the abbreviation for Atlantis until something becomes more official. I think it fits well with SG-1.
Anyway, does anyone else think that the music in the backround of the commercials promoting the premiere episode of SG-A (Rising) will be the same music (but more complete) used in the opening sequence of Atlantis? If you taped it, try to go back and listen to it again. I'm thinking that it probably is, and if I'm right, then I might like this opening even better than SG-1!!!
