And I agree about the trailer policy - why to close the way of free propagation of their own promotional campaign? This could save them some bandwidth etc.
Oh well... too complicated thing for us, mere commoners... the big fish up there know better... like the publisher of that flight sim I play, which does not want to release new low-cost add-ons for the game that could be used to milk the fans and squeeze the last buck out of the game engine that is readily available... no, they prefer high-cost investments only, even if it means risk.
