I don't think it's a BSG game. Firstly, he's not writing about it like it's a BSG project. I mean, read it again. It's in "Bear's Battlestar Blog" - he know's that the prople reading it are going to be maybe 2% BSG music fans and 98% pure BSG fans who like the music and everything else BSG they can get their hands on. So he knows his readership would like it if it was a BSG game, but he delivers it as "You liked that, so you might also like this".
Secondly, the recession's hitting game developers too, so any dev house that got the contract to make a BSG Game - pretty much the hottest property in Sci Fi at the moment and a nearly guaranteed moneyspinner - would be crowing about it. Or at the very least make a stock exchange announcement to get their share prices up, which would rapidly leak into general Gaming/BSG newssits. In short, if a major BSG game was in development - and, for that matter, had made it to the music stage - we'd know about it.
