I don't think Steam ever generates keys unless they're Valve games. My understanding is that Steam is just given a list of keys by the publisher, and when they run out, they need to get more. The same thing happened with F.E.A.R. and Prey a while ago, too. Apparently they usually have enough that running out of "stock" isn't a big enough concern to add the necessary billing logic.
