Might be too early to ask this question really but any sort of answer from the dev would be great. The game looks awesome and I'm planning to do the pledge soon, then I thought about if it'll be on steam or not. Mainly because that I've been using steam for so long and it feels awkward without it, it's all personal peference and I know steam has its flaws and such but I really hope it'll be launched on steam. And by that I don't mean using steamwork and being exclusive, but just avaliable for steam users.
I would love to see this game on Steam as well. Not only would it make things simpler for those of us who love using Steam, but it could also get a lot more people to notice the game and buy it!
From the FAQ on the kickstarter page: They're going to try it at least, and it doesn't really look like something Valve would outright deny, so there's a good chance.
