One of the last questions asked was:
"What will the create-a-class system be in multiplayer? And will we see never-before-seen perks?"

To which Michael Condrey replied:
"Were days away from E3 2017 and the team at Sledgehammer Games can hardly wait to share more on our multiplayer plans. Were particularly looking forward to revealing more on Divisions. Divisions fundamentally redefines how players invest in their Multiplayer soldier career. Replacing the create-a-class system, players choose from five iconic World War II divisions each with specific basic combat training, division training and weapon skills. We think itll intrigue Call of Duty series veterans, and we cant wait for our fans to see it for themselves."

Maybe "Divisions" is somewhat similar to the Battlefield series where there are different roles such as Assault, Support, etc. and in each role there are different weapons, perks, and attachments
