I keep hearing that Wave 3 is a go, according to funko's funkofanatics.com site... supposedly it comes from someone within the Funko family. It's just that the figures haven't been revealed yet.
But it's tough to know how they will approach the line. I mean, there are so many characters they can do, but where is the line drawn? Rickon Stark comes from a prestigious family, yet his role is so small that does he warrant a figure? Bran? Well, it would make sense if he came with Hodor.
