If you managed to miss the news, Fallout 4 has just been announced! The site is pretty barebones right now, but the trailer looks pretty good! Seems the early rumors were correct and it will take place in Boston (you can see the USS Constitution, Scollay Square, the Paul Revere Statue, and a couple other landmarks in the trailer).
The graphics are definitely improved (it may be using a modified version of the Skyrim engine as they used a modified Oblivion engine for FO3).
Seems we will learn more at the actual reveal on June 14th!
