This is a very interesting development. It's like Steam's answer to Kickstarter, but with no go/no go goal. The remarks don't seem to indicate whether the feedback will be restricted to purchasers only. Currently, Steam forums are totally open. You'd think that the devs would want to restrict the forums only to people who purchased the game.
