Well this lifts some doubts from my mind. When I first heard it was going to be set in America, my first worry was about his name. American names are really boring. Altair and Ezio had really cool names, and I was worried that this guy's name was going to be John Smith or something equally as boring. I'm glad he's a Native American though, they have some pretty cool names.
It appears that the next game in the series will take place during the American revolution and will star a Native American ancestor this time around.
Good to see the game industry is moving beyond the typical "White protagonist"
