Even if DICE finally rolls out the updates, releases the delayed maps, adds new weapons, and fixes the majority of the bugs and core issues...
They must realize by now that they have lost all credibility as a AAA studio. This game has been bleeding players since day one, and with every new problem that arises, the wound only gets bigger.
Whatever they do now, it doesn't matter. They've lost players that they are never going to get back. Nothing they do will wash away the stain that this game has left on their reputation. Even if the next Battlefield looks like it's going to be a smash hit, people will remember the failure that was BFV and the incompetence of the studio that caused it. Trust is not so easily restored once it has been lost.
