The $60 pays for the full campaign that will release episodically. That's like saying people who bought into a Telltale pass should crucify them for only getting the first episode they paid for at launch.
the problem with hitman is you're putting a downpayment on content you don't know about. it's essentially a season pass for a game that's got half the content a $60 should have. i've never been a fan of that. the idea of pre-paying for maps that could very easily be terrible.
i'm so waiting for the physical "all in" release to see how it all turns out.
