Nope. I’m not talking about the end of SGA Season 5 (although aren’t you dying to find out how it all comes together?), but Michelle points out that the company Big Finish has moved forward with selling their “talking books” for SG1 and SGA.
There is a clip available on the SG1 page to give you an idea of the production value for these things. I must say, I’m impressed. They’re less audio book and more radio production, without the large cast. (I’d link you to it, but their servers seem a bit overwhelmed, today.)
