The only reason they are going to New Vegas for season 2, is to lay down a whole bunch of Bethesda-fied revisionist history about the whole Nevada area.
They would want to torch the playing field, and make creating a New Vegas 2 that is worth a damn impossible, in anticipation of the possibility Microsoft might put Obsidian on Fallout too, after Outer Worlds 2.
