Yes, your bringing up Tudyk, he continues to be in demand (and Fillion is still leading a show). Doing voiceover is easier to squeeze in alongside other jobs.
Re: the second season for Scarpetta, my guess is that it was contracted for from the start, probably in order to ensure getting big names like Curtis and Kidman.
It may have been - but they are advertising it as based on the number of viewers S! got. (I was following Curtis for a bit on Instagram and FB and she was advertising the heck out of it and S2 pickup. I finally stopped following her - she was driving me nuts.)
I think most of the cast of Firefly is busy - and voice work allows for it to work, and they have to be between S1 and Serenity - for Wash to be in it, since ahem, he can't be in it after Serenity - well, he could...but...
