I'm somewhat interested in this but $50 does seem a tad high. I'll wait for the official launch when it'd undoubtedly be half that price.
You can get it at the Humble store as well for the same price as Steam:

Advantage here is that Humble normally include the DRM free option along with the Steam key once the game is released.
