Without knowing future affidavits and Nick's cockteasing bullshit:
1) I'm 99% Confident Monica's TCPA is DoA thanks to that Stan Dahlin affidavit. It shreds apart her claims of assault, makes her a liar. Most of what is included is prejudicial. They argue on damages, they don't argue on defamation, basically admitting to it. It looks extremely unprofessional and more like a forum post than a law document. How you can't see this extraordinarily weak TCPA for what it is, you'd have to be fucking blind. Ron also contacted conventions as well, which goes to Civil Conspiracy.
2) I'm about 65% sure about Funimation. Corps are notoriously tough and with very loose labor laws, on its face Funi seems like it has the best chance to beat it. Though what discounts their favor is that Ty and Co. can say that their investigation was incompetently done due to not revealing the Monica story or implying they conspired with Monica. They can also say they inadvertently accused Vic of crimes of which he has never been charged, defaming him and damaging him. So inept investigation that never revealed the Monica incident, possible conspiring and not telling Vic, implying Vic was accused of actual crimes. I guess this is the more controversial stance since everyone says Funi has the best chance to win. I don't think it does though.
2) I'm about 60% sure about Marchi TCPA dying. Out of everyone, hers seems like the best chance to beat it. The problem is that she claimed assault, has constant details changing and made malicious Tweets. I think the way this dies if they have a way to prove that she contacted conventions or strong-armed other voice actors and Funimation higher-ups to fire Vic.
