In FFXII, Viera have short two-syllable names that have a very Icelandic or Norse feel to them. Incidentally, Norse is where the pronunciation of Viera names comes from; "j" is pronounced like "y" in that language. I could easily see FFXIV Vieras having a similar naming scheme.

What will be interesting is what FFXIV will do with the last/family name. As far as I am aware, Viera in FFXII don't have last/family names and only have given names. I am looking forwards to how FFXIV will handle that.
