I take the Savior as the one prophesized with the most powerful Light magic (TL incarnate) that will defeat the Darkness.

So, Emma should still have her light magic because it will be stupid to somehow lose it because she is light magic incarnate. So, Emma will probably still defeat the Darkness. Therefore, Emma is still the Savor, but Regina (and anyone else) can be a savior.
