I am a fan of the first game - while it wasn't perfect, the different origins provided different perspectives on the same events, as well as the results based on choices. Those reasons that I like it were enough to get me interested enough in the setting.
True, this second game will take away what I mainly like about the first game, but it will be set in the same setting and I have a sneaking suspicion we'll see some effects or references to game one (like morigan's child, or something).
So for now, I am cautiously optimistic and willing to give it a chance.
I may change my mind as more info becomes available, but something tells me that I'll still find a way to try it myself regardless.
