Chalk this up as a possibility with a strong foundation behind it right now - Planet Iacon
have shared an image showing artwork of all six of the Classics Decepticon Seekers charging into battle together. They claim this is for an "upcoming GDO Seekers set" and sure enough, if you look at the top of the image, there is a tag for Transformers Asia, the official page for the GDO / Asia exclusive releases. If this pans out and the six Seekers all get a new release - either reissued in a set or in new decos - this will be good news for those who missed out on the whole set the first go round.
