First of all there a new trailer up for the Rome Divided DLC to be released on the 30th of this month
Secondly Rome II is currently on sale for 66% off
Lastly, if you already have Rome II, CA is offering any one of three previously released DLC as a freebee.
The free DLC offer is good through Dec 26th and you can choose from the following.
1. Wrath of Sparta---mini-campaign
2. Black Sea colonies cultures playable factions pack
3. Nomadic tribes culture playable factions pack.
Here's the link to the trailer which has a link to the free DLC's. I think you may have to sign up on the official forum which will link up to Steam after you've made your choice.
