It was a joke on how obnoxiously vocal some Symphogear fans can be.I think it has more than 10 since in the 2019 Anime UK News Readers' Choice Awards Symphogear won the category for "Most Wanted Anime License". Or maybe those 10 fans were so passionated that they used different email addresses and accounts to vote it multiple times 😆
I assume Discotek Media's release of the first two seasons are region A locked and would therefore require region free player?
On a more serious note I think someone from Anime Limited said it was unlikely they'd license the series. This was in the Discord server so I'm not sure on their exact wording.
And yeah Symphogear should be Region A. Didn't stop it being a big seller on UP1 though.
