I want to start this by saying if there has been anything in the last few days confirming that exo suits will be in zombies, then I apologize, I hadn't seen it.

However, I believe there will not be exo suits in BO3 Zombies for several reasons. First of all, Black Ops 2 Zombies didn't go along with the campaign and multiplayer time period, so what says Black Ops 3 Zombies won't be the same way? Just because Black Ops 2 was in the future, it didn't mean the Zombies was also. That's one of my beliefs for Black Ops 3, campaign and multiplayer will have exo suits and futuristic stuff, but zombies will not.

You also have to think from a gameplay standpoint. What happened when you got cornered by a horde of zombies in the previous games? You would either kill them, or get killed. But if they implement exo suits in Black Ops 3 zombies, it was completely change that, now you'd be able to escape with ease, completely change changing the difficulty of zombies (making it easier). Additionally, if they added Exo suits, they'd take falling damage out of zombies, which has always been a major feature due to the additional challenge it presents. Due to the significance of falling damage, and it's role in gameplay, it probably wouldn't be removed, and if it were removed, the beloved perk, PHD flopper would be no more.
