Hi,
After watching LOS trailer I can figure out some interesting thoughts which you could find them quite interesting too.
The lines " I loved you then and I love you now " and " I've done questionable things " .. I say those two lines are from the end of the game and more precisely after reviving her from the death due to the power of the mask. I think that he chose the wrong path which led him to kill his friends and the innocent people only to obtain the power of the mask and then be able to bring his beloved one back to life. once it's done and she's revived, he starts thinking about his sins ( because she's turned into a vampire or medusa, well I guess) and since he has killed the innocent ones, he has no choice but to accept his faith as a lord of shadow ( who will become Dracula ). The narrator line supports my thought when he says : " a pure hearted warrior will claim the power of lords of shadow as his own.. ". It's him...Dracula.
And the one who says " Don't you see Gabrial! You can bring her back ".. I say this person is Death and he will guide him all the way to become Dracula.
Another thing comes to mind which is the title itself. LORDS of SHADOW. Are they living in the shadow ? Why?! because they like to live in the dark or they can only be living in the dark places ? what about taking that shadow to a higher level and turning this world into eternal darkness?. what about a lord of darkness instead of lords of Shadow ?
Well, I just tried. Anyway, tomorrow is June issue of PSW which will reveal more information regarding this game.

Regards,
