I'll bet you guys they won't have Darkseid attacking Earth just yet, as an earlier user said, the writers are playing a long game, which might even extend into a 4th or 5th season (hey, a guy can dream, can't he?). My bet is "the echinoderm" turns out to be starro the conqueror, and his species will attack earth; maybe to retrieve Starro, or for some other reason.
