Earlier on, Randy Pitchford tweeted to look back on everything Gearbox has achieved with Borderlands 3 this year:
Two particular replies caught my eye:
So one person asked about getting a raid boss and another asked directly about the door and to both of them he said to “stay tuned.”
Now, the past few weeks on the Bordercast Mitsu has been hinting that they will be making some kind of announcement on the 31st. He mentioned it to ThiccFilA when he was last on their.
So… Put all this together and I think we might be getting some news about the door in (under) 2 weeks.
