You think they might be focusing on Lloyd and Colette because - let's see - they're the main characters? Besides, Kratos got a bunch of appearances in said trailers as well, but I don't see you complaining about that.

Trust me, I used to be a canon nazi too, but if you want to see what happened in the game, play the game, because the OVA is most certianly going to be a creatively-liscenced adaption of the game rather than a direct port from game disk to DVD.

And no, this is not because I love Lloyd/Colette.
