Guild Wars 2 Not Coming To Steam

So I'm sure some people will be disappointing. This would be the 2nd time that a developer has claimed a games absence from Steam, is because of Valves policy (remember the EA/Origin affair?). I wonder what the particular policy is? During the EA/Origin affair it seemed that Valve either wanted any DLC to be available through Steam and/or wanted a cut of DLC sales. Hopefully this is something Valve will change, because excluding high quality games on Steam, simply because you want DLC money, doesn't seem a good decision long term.
