I'm loving Lords of Nal Hutta, but I keep finding that I miss having the species rules for the Vodrans (one of the big Hutt thug races) and even the Nimbanel (the non-thug Hutt servitors). I'd love it if they put these out as a free expansion, but barring that, I hope they show up in another product soon.

I know what you mean. I like using Nimbanese for the more cerebral jobs in Hutt cartels, so some stats would have been nice.

You could come up with a home-brew stat block yourself pretty easily. The formula isn't that hard to figure out.

I could do it myself, but I can also hope that we'll see more official releases, possibly even a few free web enhancements like they've done with the WH40K products.
