[[WMG: BruceWillis' character is [[spoiler:Joseph Colton]]]]
In the latest trailer, he calls himself [[spoiler:Joe.]]
* Confirmed.

[[WMG:Doctor Venom will appear.]]
Bonus points if he's played by MichaelEmerson, thus making it the second time he's [[WesternAnimation/GIJoeRenegades portrayed the character]].

[[WMG: Even when Cobra's exposed, several military and political officials will STILL side with Cobra's regime.]]

[[WMG: Duke isn't dead.]]
[[GIJoeTheMovie He's just in a coma.]]

[[WMG: Third Movie characters]]
Joes:

Shipwreck (US Navy Special Warfare Combatant-craft Crewman)

Gung-Ho (US Marine)

Slaughter [[spoiler:A former Cobra Viper.]]

Cobra:

Major Bludd (Former Special Air Service Regiment)

Overkill (A Viper)

Blackout (A Joe who defected to Cobra a month before Relation)

Dr Mindbender (A former MARS scientist who was a colleague of Cobra Commander when he used to be just the Doctor)
* Dr. Mindbender has already appeared in the first G.I. Joe movie as the scientist who first experimented with nanomites. His name can be heard in the message from Destro playing on the computer screen as Rex Lewis enters the compound. Dr. Venom on the other hand...
Serpentor [[spoiler: A resurrected and brainwashed Duke as a Viper]]

[[WMG: Zartan isn't dead.]]
The nanomites heal Zartan's face when he cuts it with a knife. Being stabbed through the chest is more serious than a cut on the face, but who's to say they can't heal that. It might just take longer.

[[WMG: Destro isn't dead.]]
It was never confirmed that he died it the explosion.

[[WMG: Scarlett isn't dead.]]
[[HesJustHiding She's just hiding.]] Or on another mission that precluded her being called back, or something.
