I'm, not sure, quick google search says we've 5 still unaccounted for, so yes, it would seem, though given they've kinda "ended" their's and the Garlean plot I'm not sure what they plan for them, if they'll just be "killed off" off screen, they'll show up as minor/major bosses or hell, perhaps we'll even work with them, if Gaia and Danny showed us, it's they really only were all kept on the same page loosely by the unsundered and it feels like that may have been less willing and more, "here have memories, ignore what I may or may not have done to the last shard of you." *zap*
