It might have been only lip service to boost marketing. It might have also been failed project planning, where the project and implementations how exactly the community will be incorporated have not been laid out properly, then game development lagged behind, Relic fell into damage control and panic mode, went back to the normal dev cycles that everyone knows and community was low priority. This would be in line with the fact that they started out with a very early, surprising and well communicated alpha test, but did not plan for a MP test and only squeezed it in after delaying the game.
Nah probably DevM got assigned to make cofee for the art team.
Joke aside Relic couldn't keep up to their word and the recent Q&A shows how out of touch they are with the community. I respect AE and anyone else who still believe but honestly its just pure hopium at this point
