It is indeed in a blog post that the developers of Need For Speed have released a few details about the next episode, which will be released this year and will be fully revealed at the E3 during the Electronic Arts (EA Play ).
Here is a short summary of what we know now:
-The game is under development at Ghost Games and will be released at the end of 2017.
-This episode will make a great place for the customization of vehicles.
-The police will be present on the game, including large 4x4 rams.
-Graphical progress is obviously expected, with environments that look more varied.
-A "systemic" dimension is to be expected ("We create the game universe, but what we are most passionate about is what you will do")
-No need for internet connection, so you can play solo without being connected to the Internet ("yes, that means you can pause the game", yay!).
-The big reveal will take place at the EA Play conference, just before the E3.
