I hope Universe 7 and 6 make it to the end and in a surprise twist they have an equal amount of fighters when the time runs out. This way both Universes people have the emotional investment in remain, and the loss of the other universes isn't magically undone (perhaps something is said like Super Shenron can't undo Zeno's erasure. It would make sense since Zeno's erasure worked on a being made immortal by Super Shenron (Future Zamasu).
