RUMOR: Possible DLC Map Editor in the future for Killzone 2

In a recent "Ask the Dev" thread made at the Official Playstation Forum Boards, Seb Downie (QA Manager of Guerrilla Games) was asked by a Playstation member this question –

"Does Killzone 2 engine make possible a future DLC Map Editor?"

And this is what Seb had to say in reply

"Tough one. But it is something we’ll keep in the back of our minds for the future."

Now this is definitely a "RUMOR" as of right now (as headlined & channel typed). But what are your thoughts on this topic, gamers?
