http://arrstatus.com/ this lists all of the servers currently, however they may end up having to create more by launch. The ones listed as legacy will have characters from 1.0 while the ones simply labeled Japan, North America, and Europe will be fresh start servers. Legacy characters will not be able to transfer over to the fresh servers for 6-12 months.
I think a lot of people in this forum that are starting over are going to be on the Ultros server. At least that's the one we are all on for the Beta.
