Its sounding more and more interesting, so here is the recap strong leaks or confirmed -
New game modes
Weather changing maps including storms and more natural disasters
Day to night or night to day changing
Game cinematic trailer next week
Battle log to come back - I really hope they give the servers back to the communities !
Servers to be balanced
Only next gen consoles and PC will be able to play the new battlefield, older consoles the game will not be available due to not being able to handle the specs of the new battlefield, interesting to see what the pc specs are going to be for min requirements.
I believe most of this is posted in the vids with a host of other stuff, so any leaks from Tom Henderson are very accurate, he already leaked so much stuff before Dice have officially announced.
Fingers crossed this will change Battlefield for the better.
