Very long back wasn't there something about there being over 30 characters; exactly 39? This leaked info could have some credibility from back then. I also did assume that if it were true that most of them would be bonus characters. However the one who posted it is a new user so he might be bullshiting us for some attention. Plus I bet this person read some of our posts to make it look more legit.
Also, if Talim is intended to be the same age as before she did come across a shard of Soul Edge and I think she also felt the presence when Siegfried became Nightmare. Though they could also have her be born sooner than later. I know it is still early to judge, but this still feels more like a remake than a reboot.
Finally what is it with wanting a new female character? I would actually not want that in favor of having one of the old favorites return. I would rather have either Cassandra, Hilde or Setsuka to have a slot than a new female character. If they have to she better be worth it. You too, Groh.
