Before Imu i liked the ideia of Akainu trying a coup against the Gorosei ans transforming the WG in a military dictartoship, but after we learn about Imu and them about Nika, it become impossible, as Oda clearly want Imu to be the final villain, as he is the anti-JoyBoy and Akainu become just a minor subordinate.
Still think a part of the Navy will try a coup, but will be the good guys as they join Luffy side in the final war.
