0.7 is a long way off.
I'm currently in the middle of redoing the entire item list and the troop trees.
The culture of the free cities is being completely changed, from a graeco-roman mixture to a byzantine-arabian-italian city state conglomerate.
More information on that soon, pictures coming once I have a good batch of new models and textures.
Other new features in 0.7 will be:
A completely new world map, much bigger, more detailed, as close to canon as possible.
Many new scenes. Amongst them Saltpans, The Eyrie, Casterly Rock and Harrenhal.
New factions. Secret for now, though it's something many people have been asking for.
