IPV6 has a lot of advantages, not only for ISPs or RIRs. The use of NAT would be eliminated and the overhead is smaller just to mention a few. It may or may not impact a single user by itself, but as more and more ISPs, Apps (and games), and users move to IPV6, the impact in the massive side will be great for everyone. The game and Servers networking should improve in the long term and the implementation should not be difficult since the game is not using a lot of DNS.

Just hope PS4 also accept it soon.
