Unless they are using a completely new engine then I'm not interested. The Warscape (I think, basically Empire onwards) engine just doesn't seem to work properly for battles. Too floaty, no real weight to anything.
I think it's true that they need to retrace their steps backwards, then go forwards again in a different direction.
The whole R2 project turned out to be a stinker. Shogun 2 was brilliant. Somewhere along the line when development started to move from one to the other, they had a major brainfart. It's like the whole project itself was mismanaged from the off and it seeped into every facet of the game.
