I think the day TW integrates a bird eye view and control to the troops, this game will be taken to another level.
I'm not sure people would want to be on that level, because that's not what the game is about.
Total War provides battles at a macro perspective. Even with a lot of restrictions and realism settings on, it doesn't change the fact that you, as the commander, know everything that's happening around from a birds-eye-view instantly.
Mount and Blade series, was always about the personal experience, in the first-person, as a single solder actually standing on the field. And the view from the perspective of that single person is very different from the entire order of battle and formation info made available via a tactical screen. Stand behind the ranks of your own men, and immediately you are engulfed with lack of clear sight. You have no way of knowing how the enemy is positioned over that hill or forest (well, left+ALT ruins it a lot, but it does provide only limited info, thankfully...).
This means, commanding an army as the person that's actually part of that combat on the field, can never be the same as commanding an army from a perspective that offers the entire view of the battlefield.
I love both Total War and M&B franchises, but for different reasons, and I really don't need to have this game homogenized under the standards of a different game, that's supposed to be played differently.
