The studio previously announced several projects in the Fallout universe. One of them is Fallout 5, but its release is expected in 5-10 years, as The Elder Scrolls VI will come out first. But after that, fans can expect new releases.
Rumors about remasters appeared after a major Microsoft leak related to the acquisition of Activision Blizzard. It was then said that Bethesda was working on remasters of Fallout 3 and The Elder Scrolls IV: Oblivion. The announcement of the Oblivion remaster confirmed the speculation, which increases the chances of Fallout 3 Remastered being released.
But, apparently, that's not all the studio has planned. Recently, an X user wrote about rumors about Fallout 3 and expressed regret that New Vegas would not get a remaster. To this, Windows Central editor Jez Corden briefly replied: "nv will be out too".
There is no more detailed information, but given Corden's reputation and his reliable leaks about Microsoft's plans, one can cautiously hope for a Fallout: New Vegas remaster.
