We might eventually do separate entry/exit addresses for IPv4 too, but that will take time since all of our current IPv4 addresses are known since we've already disclosed them, and it will take time to order new IPv4 addresses for all the servers. Instructions OpenVPN users should be able to use the new IPv6 addresses immediately, as long as IPv6 isn't blocked by a firewall or disabled in the OS.
