Overwrite-whether in the future history of the world of Fallout? (Fallout 4)

The fourth part is quite away from the canons - from small things, like the pre-war screw and ending with the almost complete loss of the retro-futuristic style. Technology and political realities of the pre-war world is also close to the modern - in one of the bunkers hanging modern map of the world, and the way of life of Americans of the ' 70s of the 21st century, contrary to the Canon, not much different from the late 20th -early 21st century. Even the war with China and the Soviet Union any longer (though there is a quest with a Chinese submarine), and some phenomena appeared quite different explanation than was in the first parts of the game (for example, a mutant suddenly appeared the results of experiments of pre-war scientists, or suddenly spread to the entire mainland of the virus re). Further - more, to be released the 5th or 6th game will be a complete restart of the series? With the rewriting of the Bible and Fallout new history of the world, more suitable for modern concepts and ideas about the future.
