I appreciate and hear all of that sales talk, but none of it really matters until the unwashed masses of gamers get their grubby hands on all of this stuff. I've seen too many grand promises that fell flat to actually trust it properly now, even if it's coming from valve. They're doing something bold, but that doesn't mean it'll work as great as people think it will.
That's also worth saying, I've seen Valve flop, crash, burn and neglect too much in playing dota 2 to actually put the same amount of blind trust in their product like a lot maniacal fans right now.
