Age of Empires III datadisk

Ensemble Studios are preparing new datadisk for age of Empires III, called The WarChiefs. So, what we can expect form it? All three new nations will be indians, seems authors find indians easy to make, or mission designating. One of those nations will be iroquese, hopw they will will be nice and brutal. (btw, they will use many european inventions, such as original indians.) And also many events in missions should be true history. (Hey, i want box of whisky and sme arrow packs, and go buy manhattan!) AUthors of course want to release it as soon as possible, but they also dont want release incomplete and untested game, so it should be available during autumn.
