The latest issue of Non-Sport Update has a Wacky Packages Halloween comic book listed as coming out in October. Not surprisingly, there is also a Halloween postcard set listed as being released that month. And Wacky binders in September.
Not to get too far off base (perhaps this should have its own thread), but there are a bunch of GPK issues listed as coming out soon that sound intriguing. Besides binders and a Brand New Series 3, there are "minikins" and greeting cards. Also, an online exclusive of "mini stickers". I wish Wackys were getting quite the same level of love as GPKs, though I suppose it's fairly close. I do think a set of Wacky greeting cards would be awesome. Perhaps if the GPK greeting cards sell well, Wackys could get their own set.
