Fallout 76 was teased overnight, with not a whole lot of information outside of a few leaked tidbits as well as what is known about Vault 76 from previous Fallout games.
EB Games seems to have more information that what was revealed from the official channels, with them claiming that the game is coming to PS4, Xbox One and PC in 2019.
Whilst Bethesda is known for announcing their games and releasing them in the same year more often than not, RAGE 2 was recently also announced and isn’t coming till 2019. With E3 only a week away, it’s more than likely EB Games has received information from Bethesda ahead of time.
Usually EB Games will list a game as TBC unless they’ve got a confirmed window and as we’ve learned from recent retailer leaks (hint: Walmart), retailers often have this information well in advance.
