Everything else that’s planned for November 28th is still in place; that includes Legacy-wide credits, a character boost item to bring a character to 70, a new flashpoint, a new boss in Gods From The Machine, and many more things for players to do. (Also improvements to group finder queues, so it’ll be easier to find other players to do things with.) You can even read some new lore exploring the events leading up to the next set of quests centered around the traitor story. You’ll just need to wait a little bit longer for a new warzone, that’s all.
