Give it a rest. They pick civs that will be interesting and diverse. That's why they have Austria but not Portugal (who is fairly similar to Spain). They added Mongolia, Inca, Polynesia, Babylon, and Korea as DLC (three of them Asian, one has origins in Asia). So the DLC was fairly multicultural, while the expansion is more Eurocentric (and, even then, two of the civs have origins in Asia).
Personally, if you ask me, this strikes me as possibly a bad business decision in that European civs likely would have sold well independently, but that's beside the point.
