You can make a strong bet that it will be M purely on the fact on how strict the ERSB has gotten lately. Heck they could give it a M rating purely cause you have guns and are killing things because it has been awhile since I have seen a FPS come with a T rating. I personally don't care if their is language as that doesn't make the game for me. The occasional is fine and yeah would be expected if that happened in real life, but the overuse of cursing especially of the "Fbomb" is due to a lack of creativity in writing which is not serving this company has. I mean heck the Elder Scrolls Online just got rated M and they were "shooting for a T rating"
