I think it's all in the way it was phrased. The way he said it seemed to imply that having many bisexual romance-able companions was a bad thing rather than what he meant: (I think) that having a larger variety of sexuality in romance-able companions is a good thing.
I believe you inquired about this previously and didn't get a reply. Sorry about that.
When he says that some characters in DA:I will 'just being one sexual orientation,' the implication is that some of the previous character's *didn't* have one sexual orientation. After all, if he viewed all the previous love interests as having a defined (if not explicitly stated) orientation, it would be an odd thing to note that as happening in DA:I.
And most likely what he's referring to are bisexual characters. I mean, I don't think he's implying that Morrigan or Alistar didn't have 'one sexual orientation.'
I've been hit with a few PMs as well, and I think I understand. It's definitely not the way I read it (I consider bisexuality to be a "set sexuality."), due to prior biases and general inexperience with the topic, so thank you for the clarification.
It seems like it'd also be increasingly jarring to those that feel that DA2 was simply 4 bisexual companions, because it'd certainly come across as "There were no set sexualities in DA2" or "The bisexual companions of DA2 do not display a set sexuality."
I do want to echo Shorts' statements, that discussion about the ambiguity (and whether or not it's a preferred thing) was actually one of the larger topics at the BioWare base during PAX Prime, so the idea that there are people out there that consider the sexualities "ambiguous" or "open to interpretation" are certainly out there and certainly not a small/trivial component.
I have to imagine he's under some sort of ban on what he can and can't tell us in regards factual information.
Just to be clear, since I see this come up a lot in a variety of places. I'm not under any sort of ban in terms of what I can and cannot say here... I am simply trusted to not overstep my bounds. Which means I tend to not speak definitively on very much until "higher ups" tend to speak on things. I don't know everything, but I know a lot about a lot of stuff that I go "That hasn't been discussed yet, so I won't bring it up."
As stated, the reason why I engaged in this thread is because Cameron is quoted as talking about it (and I wanted to mitigate the outright trolling and derailment posts) so I have less reticence to chime in about it.
