In a recent studio update, Creative Assembly confirmed that a new Total War Saga is in development and will be announced later in the year. The Sofia studio is once again at the helm, though it's also working on other projects. Details are slim, but it's apparently passed its first milestone. 

Sagas are, in concept, pretty neat. They're focused Total Wars that cover a briefer time and smaller place, such as Alfred the Great's wars against the Danes in Thrones of Britannia. It's something Creative Assembly experimented with back in expansions like Napoleon and Fall of the Samurai, both of which were series high points, though the first saga left something to be desired.
