Just so I'm clear, you'd be more satisfied if it was confirmed that Cassandra and Cullen were exclusively heterosexual (this is NOT a confirmation of that)? It certainly doesn't really strike me as "equal" information though? I think that there'd certainly be some very upset people if that information was revealed....
Well, I don't want them to be. lol I mean, it would be a slight let down and I wish whoever is in charge of the announcements would pick a bisexual pair first, so the initial excitement of romances could be spread around equally. I wouldn't be angry about it, though. In the end, it doesn't make much difference. Somebody would have to deal with an announcement where they weren't represented at some point. I'd feel it was more fair to be told if they were available NOW, when heterosexual people can be basically assured they're available to them.
If they're going to be heterosexual, though, I think less people would be angry knowing now. It gives people less time to get attached to the idea that they'll be available. They'll be angry at some point, either way.
