Yeah, I brewed something pretty close to a Saison with the Wyeast Belgian Specialty private reserve. Same deal, where I bottled at 1.010 after about 3 1/2 weeks. I ended up with a bomb, though (there's another thread about this). Haven't ever had a bomb in 1 1/2 years of brewing, so it's a huge surprise.
No real input, just agreeing that FG 1.010 seems pretty low.
