SR never had a full reset.

And honestly, there is no way a full reset is even possible that this point. What's most likely going to happen is that they are going to toss in another Yakumo arc, a couple arcs to wrap up whatever supporting characters are left, and then one final arc with the conclusion that will end in one of three ways:
If it's open, we will rage. But it would still be the end.
