If the leaks and rumours are right, then Fallout fans will be witnessing Fallout 4’s official announcement at E3 this year. If that is to happen, then when will Fallout 4 be ready for a release?
Upon researching on the release pattern for previous Fallout titles, there is no doubt that Bethesda will launch Fallout 4 in fall next year. Heck, Fallout 4 should be available in October to be more precise.
In detail, it normally takes Bethesda about 11-months to release a game after it gets announced. This was the case for both Fallout 3 and Fallout New Vegas, thus, the pattern should repeat for Fallout 4.
In between the announcement and the debut date, Fallout fans can expect Bethesda to go on the many gaming events to tease on Fallout 4 like launching its teaser trailer and such.
