Little is actually known on what the series will be, beyond the generalized pull quotes from the siblings and Netflix, "A gripping global tale of minds linked and souls hunted." and involves "the ways technology simultaneously unites and divides us." If I can speculate, Sense8 implies a teacher/student dynamic, and the Wachowski's have always been interested in gnosticism and martial arts, so this seems like a good guess.
