They always release this kind of stuff in December when everyone has their head in the wrapping paper.
One thing is sure, they already have their sights set on someone . . . and that someone will be exposed come March / April.
From there, it will all become a lot more clear.
how does this affect affiliate marketers from other countries? for example i'm from germany so do i have to care about the new rules too?
If you're advertising in the U.S. you have to abide by their rules. Similar to selling a car here, you have to pay our taxes, you can't avoid it just because you are from Germany (you can, but they'll come after you).
That couldn't be further from the truth...
