Ask Cryptic for Champions Online falls under that category, with several questions about upcoming features given a straight denial. There are no plans for four-armed characters, rotating and scaling tattoos, and a current push for more persistent content as opposed to zone-wide attack events.
On the flip side, the answers do paint a few interesting pictures, such as talk about potentially adding a villainous counterpart to the game in the vein of City of Villains. The idea is discussed as something not in the immediate future, but on the list for future inclusion -- albeit with a much more sandbox style of gameplay, keeping in the vein of a supervillain romp. Champions Online is currently pretty well dedicated to getting its existing systems shored up and working well, however -- and while that might mean a few rejected ideas, it means that the team wants to build a solid foundation.
