There's been a few rumors floating around about this. Now we've got official confirmation. Fantasy Flight Games and Games Workshop are concluding their business relationship with one-another. The agreement, which started back in 2008 will officially come to an end on February 28th, 2017.
What does that mean for Games Workshop products that Fantasy Flight makes? Well, they won't be available for sale in the Fantasy Flight store anymore. Also, no new releases will be coming out for them (obviously). Everything that has been announced will still be made and distributed, but that'll be it for those product lines.
