I think they'll go with the troubled hero routine. Adora will find out who she is and she'll probably receive the power of Grayskull by the end of the series but this time she isn't under any spell. Every choice she made was one she made contiously and she'll probably head off and take her time putting things in perspective. We'll probably see her again on occasions where she is really needed or if they accidentaly bump into her, sort of like Zodak or Mossman in the 200x show. I can't see her becoming the She-Ra we saw in the 80's. This version might have some rough edges. I don't think she'll get a spinoff though.
And this is also how I would like to see She-Ra handled.
