What will be the next threat in that case? synthesis=utopia. I guess everyone will be peaceful and possible threat must be only from other galaxy. but what kind of enemy? you will have thousand of reapers on your side cuz synthesis will save them ( still can't imagine something stronger). but maybe BioWare not planning invite guys from another galaxy and all actions will be only in Milky Way.
