How awesome would it be if they created a new faction and new characters for the next game ? I mean imagine a faction of people tired of the horrors of war and they decide to take a stand. They could be a village of fisherman's , have a flag with a shark on it and they could be called Shayu. Then their leader would be a dude with a fishing rod as weapon. So many ideas... xD They should go further in the next game , still DW8 its probably one of the best i played in the series so far.
The answer to what this is, is that the TC is unaware that Dynasty Warriors is based on an established novel, which is in turn based off of a real historical era.
One cannot just add new things to a story based off of established lore/history... unless they have long legs and big t***...
Now if you want a new faction... Yuan Shu or Liu Biao would be your best hope. But Don't expect to see them until Dynasty Warriors 10/11. By then most of the major players will be a part of the Wei/Wu/Shu rosters and they will have to look elsewhere for improvements.
