Associate Design Director on Star Wars Battlefront II, Dennis Brännvall, has commented on the possible debut of General Grievous in the near future.

Rumors about Grievous being introduced in Battlefront II surfaced after a 3d model for the villain was found in the game’s closed alpha game files. Various heroes and villains have already been announced for a post-launch debut, but the coughing Kaleesh cyborg general has yet to be confirmed by DICE.
