It's the same issue from before, You can PLAY but if you're using a crappy server eg any free server, and you get banned you cannot change your KV because it's down just like how it was down before for like a week or so.
Those who are using Ninja don't need to worry because KV life is so good you'll probably be back.
But now it's time to sit back relax and wait for the hosts to come back up lmao.
the Black Ops 2 Issue, I've no idea, could be related because backwards compability obs it wont work on either console, might be same for other games. although a lot of people are going to freak out thinking it's the end of the world.
