I would guess that they aren't committing to anything at the moment because they are experimenting. They started the Deal of the Week in response to people loudly requesting something like it, same goes for putting more games on Steam. They recently had games on the Humble Bundle and Steam's deal of the day. They are branching out and trying different stuff.
Yes, I understand that but an answer one way or the other would be a kind and good business thing to do! I've supported this "Deal" since it started as I'm sure many others have too!
