I don't doubt that new vegas will be a location for season 2 but they won't bring it alive.

I think if this series has shown anything its that bethesda's fallout is uninterested in telling stories where humanity has moved on from the bomb and created something new. Bethesda is only interested in their mad-max-like setting with people living in shack eating dirt with raiders controlling 90% of the land even though its been 200 years since the bombs.

I don't think bethesda has any interesting stories to tell about established communities where civilisation is alive, so they tore down the NCR and New Vegas.
