No, he won't be writing for it, but he does have something to say about it:
Not quite as good as Lost, but far better than Star Trek, in any of its incarnations — sorry, Trekkies, but you know I speak the truth. This is a beautifully written show, driven by character rather than effects...but the effects are damn good. And there's not a better acting troupe at work on television. (I get it via computer download, probably from the Cylon Empire.)
From a column that he wrote for EW magazine, where he talks about several other shows. Take a look here.
