I'm still looking forward to the game, but a little less so. DA2 was a nice surprise because I could finally create a character and play however I wanted when it came to romance. It was so refreshing.
Because it's the Dragon Age team, I feel a bit more comfortable with the decision, but I'm cautiously optimistic.
I'm taking more of a wait and see approach to the game, because we don't have much information and probably won't until it ships, but I can't help but be a little worried. What I don't want is another NPC being the designated "same sex." Don't get me wrong, Samantha was okay and I actually really liked Steve, but I'd like to see a fully fledged gay/lesbian companion, and I would say, not only a companion, but one that is completely integrated into the plot. I don't mean the incidental involvement a la Leliana or Zevran, but a Morrigan or an Alistair.
Pros
A prominent gay or lesbian character being integrated into the main storyline has the potential to be truly groundbreaking.
Cons
Certain romances won't be available and that means people will inevitably be disappointed.
Gay, Lesbian, Bi, Pan characters won't be fully integrated into the plot and be left by the wayside again.
Content will be unequal and biased toward heteronormativity.
