An official thread by Bethesda on NeoGaf mentioned that their next game in the Fallout franchise that sat the internet on fire with its reveal won’t be coming to last gen consoles due to technical reasons.
According to Matt Grandstaff, the RPG game Fallout 4 would never work on last gen consoles, saying that the “stuff we’re doing will never work there”. What kind of stuff is still unknown but it’s expected that Bethesda is keeping a shut mouth on the game’s features so we have to wait for E3 to know what might that be.
On another note, many speculations and rumors have been going on when the game is releasing. As many retailers and websites like Amazon were spotted listing the game for October 2015 as the release date for Fallout 4. Of course nothing has been officially confirmed so take that with a grain of salt.
More info to be shared with the world at Bethesda’s first-ever E3 conference.
