Still Mildly Glowing
It is still likely in unexplored parts of the Wasteland that there is civilization going. Just because Portland, Seattle, Toronto, Richmond, Houston haven't had contact with the NCR that there aren't new nation states forming their. Like one of the posts before me said, if factions can make their own stuff, why scavenge the ruins? This is happening in other places, so either the games will become more focused on themes of rebuilding in a post apocalypse or start having games set early in the series in new locations far enough removed from California to not interfere with the other games.
