Although Bethesda has yet to officially confirm Fallout 4, an informant who allegedly knows the PR officer for Bethesda seems certain the game is in the works.

"First and foremost, the game will take place in Boston, and be kind of a direct sequel to Fallout 3 with a few groups returning," said the informant on Reddit. "From what it sounds like, 'The Institute' is pretty much the downtown DC or New Vegas of this game. Boston is going to be unlike anything we've seen in a Fallout game before, with buildings more on par with cyberpunk and retro-futurism."

"Androids play a big part in this game. The railroad from Fallout 3 is a faction. The enemies of the railroad is "the Plantation" - a group who force Androids to farm so that Humans can get food. The Institute is highly advanced and probably obtained or built their own GECK to start a farm. Due to complaints about using Super Mutants and the Brotherhood of Steel in Fallout 3 excessively and going against the lore too much, Bethesda has decided to avoid using these groups. Bethesda wants to make a new "race" (think Ghoul, Super Mutant) which will be central to Boston. Bethesda is currently looking at Lovecraftian fiction since Boston is around 'Lovecraft Country.'"

"Bethesda has no plans to reinvent the leveling up system to make it more like Skyrim and want to make Fallout 4 more distinct from Skyrim since of the complaints that Oblivion and Fallout 3 were too similar. Bethesda is thinking about introducing a system, similar to Skyrim, where your skills can level up if you perform certain tasks."

It is believed that Fallout 4 will have a release date set for Fall of 2015, and will make an appearance at E3 that year after missing this year's action.
