Will we ever get more information eventually, or only after accidentally winning them? Haha
You will know when the time comes. I hate to say things will only get more confusing and frantic, but knowing our badge-hunters, it's only inevitable.
I will say, however, that you can not get them yet. It will be obvious when you can. Consider their early appearance a sign of amazing and great things to come. You've never seen something quite like it.
