Shortly before Classic Media announced they reached an agreement to license MOTU stuff the guy on Twitter started inquiring about whether people would want to see She-Ra/they had interest in reviving She-Ra.
He is the creative head at Classic Media, his job is to get new shows off the ground and he was one who worked on getting Voltron Force off the ground. Its not rumors he is completely 100% legit and has been interfacing with Tallstar for a number of weeks now. He also joined the org or at least reads the threads here.
His tweets basically gave us the insight that Filmation rights were with Mattel, after SDCC these are his newest tweets. There had been some hope something would be ready to be shown at SDCC but that did not seem to happen.
