I just got an idea and not sure if anyone comes up with it yet.

I'm sure we all notice about the concept in ACIII that we might not sure who's right or wrong, templar or assassin but they share the same goal.

My idea is why not Ubisoft create the series represent the story-line focusing on templar side, of course, you can parallel some of the story-line to the Assassin's Creed series and called it like "Templar's Order" or something, that way you might expand your locations and places.
