Something I didn't realize until I read up on the Kung Fu project, not only did the CW pick up The Republic of Sarah from CBS, where it was developed last year, but it picked up Kung Fu from Fox, where it was also developed last year, so each of those projects had full crews already in place, which, to our knowledge, DS:R does not. So given that, I can now easily understand why both of those projects were given pilot orders ahead of DS:R.
Also, given that the CW supposedly still has openings this year for two more pilots, I wouldn't necessarily count it out as potentially getting one of those openings. But if not, and if the CW is high enough on DS:R, they may hold onto it for somewhere down the road, or even one of the CW's sister networks may move ahead with it. I suppose only time will tell...
