next villain? yeah, will be like new reapers with indoctrination stuff. but it sounds weird to forget them, even if it was DLC. they should play a role in next ME, they are too strong to ignore them. also, the ability of indoctrination is much stronger than reapers indoctrination ( indoctrination by reapers is killing you but Leviathans can do it without harming you)

they can't build new reapers cuz reapers were build by AI orders. so they can try to build new AI but it must gather information during long time and only after that create something like reaper. and don't forget that Leviathans may not be interested in creating new AI. the fact is, that Leviathans survived by a miracle. Not a lot of Leviathans now and probably they don't want to create new AI, cuz they can be completely destroyed once and for all.
