I'm guessing and really hoping...

Aget II is the simulated battle system. Gone will be the battle reports and players will be able to engage in a flash created battlefield where they can command their units and make strategic choices in battle. It won't any longer be just a math calculation, and the spitting out of a report.

If this was done and they worked on nothing but the battle system as an expansion, I think it would bring out a lot replay value as the battles would always be interesting.
