It is possible that it is really happening. Nintendo isn't just going to sit around until all of the people find about R4DS, M3, and other cards. Some of the sites that sell R4DS and other products have already gone down. It is not just R4DS but others as well.
It's just like I said a while back......stupid kiddies rubbing it Nintendo's face on their own forum may cause Nintendo to do something about it. Maybe they have. I have 3 R4's backordered form RHS.....wonder if I'll ever get them.
