Hello TheSnvGamer,
The map set for the event will be in Second Assault and Dragons Teeth maps. The group of DICE Developers that will be coming are primarily from the LA office which are the ones who designed those DLC's and maps. Maybe in future events it will be normal mode or all maps. Otherwise after the main Zombie Event players will be around all weekend playing when our servers return to normal. Ill talk with leadership to see that once the event is over on Friday that we might have one of the servers running all maps on a zombie server.
