I'm looking forward to Side Jobs
, but I've got a bunch of other books I need to get through first, so I'll probably wait until Christmas for it.
As for Butcher's next series, I remember him briefly discussing an idea he had for a science fiction series about a human law enforcement agent working cases across the solar system, which by that time has been heavily colonized by humanity. Something like that, anyway. That was a couple years ago, though, he might have come up with something different since then.
