I haven't seen this mentioned in any of the posts yet, but I haven't been able to get through them all on this thread. PC Gamer announced the release of this DLC with the following statement:
"The Polynesia pack will add the Polynesian civilisation and new research trees that can be used to unlock new cultural wonders like the Moai stone heads of Easter Island, and military units like the Maori Warriors."
I wonder what they mean by the bolded statement. Is it simply going to add the new wonder on the existing research tree? It wouldn't seem so by the statement. Are they going to add a new branch? Or is something else meant by the statement? Does anyone have any insight into the statement?
