in case no one noticed, you can download a new MTW2 video at the new totalwar.com (gallery > video).
It's still quite poor quality, but IMO it looks good. No cavalry plowing through endless rows of infantry like we saw in RTW trailers. It looks much more static now, which means slower gameplay. Let's just hope all the combat penalties/bonuses from MTW/STW that were missing in RTW are back aswell (ex: penalty when surrounded, disorganised, too crowded formation, ...).
