But really new content will be in the next beta phase which is expected for october.
In the News from today they say:
We're hoping to release beta 1-A in a week or two that will include things like more strategic elements to the maps, potentially a new Demigod to play with, and a number of new gameplay changes. I think people will be surprised at how quickly these betas will improve the game play and "fun" factor of the game. Stay tuned.
