It's still kind of early to say, I think. We aren't seeing multi-packs yet (though I have my fingers crossed for Randor and Marlena). As for exclusives, their obscurity probably isn't an issue given He-Ro, but then He-Ro was mentioned in two bios prior to being announced. When we start seeing PoP bios, we'll probably get a better picture of potential PoP con exclusives. Right now, I kind of doubt they will be sold together because they would need a lot of new parts, and I don't think one of the three will be an exclusive while the other two are regular releases. It'd be cool if they come out over the course of a year: one in January, one in June, then one in December.
