Fallout as a materialistic IP is dead and nothing is going to ever bring it back to our standards, but it is not a thing that is just a problem we see in Bethesda, but the whole gaming industry at large. The best case scenario is Fallout is sold to a different studio who market the series returning to its roots and releasing a below average clone of Fallout: New Vegas. All of these AAA industries ware all in it for capital. As a non materialistic idea in our heads, however, the series is still very much alive there. All it requires is for the community to work together to put out on an idea whether it be in the form of a mod or a regular video game that would be standalone, or something else entirely possibly.
