KO manifestations in the lore ?

I know it's useless to draw plans on the comet but it's too fun to not do so, I have a question :

I think we're bound to receive a manifestation lore with the new BT and people are expecting something mech or eather-related (like a flock thunderer's birds or something) and from the little I know from the lore, grungni kind of disappeared.

More wise, Is it possible that he could "return somehow" and the manifestation would take the form of prayers ?
