I'd like to point out that it's typical for beta servers to be renamed entirely for release. There's no guarantee that Gilgamesh will still be around come launch. They have confirmed that the legacy servers are sticking around, and all of the legacy servers follow the name of powerful weapons in Final Fantasy games. I suspect that Gilgamesh and the other non legacy servers that are being used in beta will be renamed to follow the naming conventions established by the existing legacy servers. Square Enix did pretty much the same thing for Final Fantasy XI, the beta servers had antagonist or monster names, the launch servers all have summon names.
Of course, this is only educated speculation, but it does give me pause about holding a vote before phase 4. People may be very committed and excited for servers that may not even have the same name come launch.
