Valve? Comment on something? Surely you jest. The ETA on Greenlight going the way of the dodo was late this year or early next, so the optimistic assumption is that Valve's preparing to flip the switch but is still hand-picking some Greenlight items in the interim.
I was somewhat (><)
But it is odd behaviour, one I would call "asking for trouble". If some major changes are underway, and it seems so, shouldn't they inform at least devs? Because you know, people keep submitting games for greenlight, we keep buying them. Totally smells like trouble...
