Honestly, I'd prefer to play as Gabriel in lords of shadow 2. I'd like his story to be told first before we divulge into different protagonists. I don't mind playing as them in a gaiden game, like what mirror of faith is seemingly going to be, but I'd like to see the end to Gabriel's personal story and what happens to him before we go to different protagonists on the console iterations.
To me, lords of shadow is more of Gabriel's story, and while other characters can show up and be playable, the central character is Gabriel.
Not to mention, I'd prefer him to not end up like Dracula. Showing up in every game like a Saturday morning cartoon villain, saying "blah blah humans bastards blah damn god blah true power blah blah", and getting whipped to death like a bdsm sadist. Dracula just lost his edge over time.
Plus Gabriel distinctly says "es sun Dracul!", I am the dragon. So, since the teaser site distinctly says "the dragon returns" and not "the son of the dragon returns (Dracula)", it'd only make sense for Gabriel to be the playable character in this one
