Yes, but those same original developers who were employed on New Vegas were still employed for The Outer Worlds; that was even a huge part of The Outer Worlds marketing - that it was being led by the same creators of Fallout 1, 2, and New Vegas.
I played Obsidian's The Outer Worlds and found it basic and unimpressive at best, so while I haven't played New Vegas I'm a bit skeptical when I hear everyone praising its story.
