Destiny 3: They have said several times over the years that making a Destiny 3 would not make sense, so there were no plans. Only thing that ever mentioned there was work happening on a D3 were leak accounts.
Considering it an overreaction is a bit subjective I suppose, but since what said was they are announcing things at the same rate, save for pre-TFS, all we had were the names of upcoming expansions... I don't see how I'm contracting myself. Unless you mean the leaks, which should always be taken with a grain of salt if you are to believe them.
I say it is an overreaction because, sure, they had a decade long story, but more than half of that was by the seat of their pants, *constantly * needing to stop moving forward and needling to fix core elements of this game. Curse of Osiris infamously almost killed D2, and without the Go Fast update and Forsaken returning everything people loved from D1... Game would've died.
I implore you to look back on Forsaken and see that it was just... Fixing D2. The campaign, while having some incredibly memorable story beats, was just... Not good. A bulk of the campaign consisted of Lost Sector like missions in the world that had you killing most of the Barons, with some bigger set piece missions spriklnkled in there.
All I'm trying to say is the only difference between now and then is that we had expansion names up front. Otherwise, about 6 months out, we would get our reveal, and them more info from there as we got closer. If anything, they are talking about Frontiers ahead of schedule. Usually wouldn't expect anything until like... November/December.
They are in damage control mode, trying to push update son content faster, but with less staff to do it. I imagine it's hell in Bungie HQ for the devs. Fuck their leadership though.
History is wrriten by the victor, and unfortunately, if you have money in this world, you're winning.
