Never happening, but let's just entertain the fantasy for a second and just ask a couple of questions.
Destiny 2 was supposed to fix everything wrong with Destiny 1 when the player base for that fell off of a cliff; how did that work out?
If incompetent development led to the game you have now, what are the odds that a new game by the same incompetent developers is going to fix it?
I do not believe the developers were or are incompetent, rather the opposite.
However they were and are governed by decisions they are taking the can for.
Now it's too late.
