Wutai is pretty populated. i just joined that server last week when i started playing. most servers seems to have almost 2 birds, theres only like 3 that has full 3 birds when i checked making my character. like others have said, i don't think there will be any server merges unless the ps3 version fails also. Age of Conan didn't merge servers till more than a yr after release or maybe even longer (i can't remember)
