Well here is some possibly very good news, Battlefield 3 Blog have just posted an article in which DICE's general manager Karl-Magnus Troedsson states...
“We have heard the community very loud and clear on this topic — that they want mod tools. We are considering it, back in the studio. The game won’t ship with mod tools, but we have heard it. I’m not saying that we’re going to do it, I’m saying that we are thinking about it.”
This could be great news, but obviously nothing is cast in stone, after all just prior to the release of BF:BC2 they released statements that mod tools were going to be available to help garner goodwill and an edge on their just released at the time main competitor COD: Modern Warfare 2 which was not going to have any mod tools, and we all know how that turned out, but still I'd like to have faith in DICE to believe that community pressure on this matter could make them about turn on this. It would at least show they do care about our opinion and desires, and are not just after our hard earned dollar.
Here's hoping that they have listened, heed our wishes and release those tools.
