What really makes me happy is this isn't going to be just a tacked on sort of thing; They're really taking an effort to do this right. To be honest, I find the "everyone is bi for the hero" approach... unrealistic. Personally, I'm hoping for a good number of the existing companions to be romancable, but I also hope a couple of the characters who aren't yet romancable will be available as SGRAs. Not sure how many of these I'm going to pursue, but I'm glad they're (going to be) there.
