This thread is really getting my hopes up for homosexual companion characters. 
Me too. If they do go with a 2/2/2 route, then it's looking more and more likely that we'll have a gay companion. Especially since Cullen is most likely either straight or bisexual, so unless they do 2 NPC LIs, one of our companions will be gay. On the lady side, it's less clear since we're not really sure what Cass's orientation will be and we don't know any other LIs at this point.
But...until Cullen was announced it seemed like the whole forum was operating under the assumption that we had 4 LI's and the 2/2/2 idea was purely a dream b/c wasn't it announced that the extension of the deadline didn't mean/include an expansion of romance resources? I'm just confused I guess. ...Have the devs really not stepped in and warned us not to get so far ahead of ourselves?
is that a good sign? or a bad one? 
Here are my thoughts on it. It's all speculation, though. The reasons why I'm starting to lean to 2/2/2 are:
1.) we know that Gaider has stated a preference for this approach, but because of limited resources, supports an all bisexual approach. With increased development time, it's not too far of a reach to hope for a 2/2/2 approach now
2.) Since we know that Cass and Iron Bull are warriors and we know that we've seen gameplay footage with the Warden in the party as a warrior, and we know that there is a 3/3/3 class ratio, it stands to reason that Cullen isn't going to be a companion.
3.) With Cullen being introduced as romance, we can speculate that there will now be at least one NPC romance. Since the game series has traditionally had 4 companion romances (plus Sebastian as a DLC 5th in DA 2), people are wondering if this means that there might be more than 4 romances, hence the 2/2/2 split.
To be honest, I'm not convinced that there are even going to be a 2/2/2 split. Even if there are 6 LIs, they could still be all bisexual (although, it seems less likely if there are that many LIs).
Ugh the fact that most people really seem to think Cass may end up male only, really worries me
It's always the 'main' characters (the ones who are important to the story, a la Morrigan and Alistair) who get to be straight. I really, really hope that's not the case and they are bi.
To be honest, this is exactly why I would suspect that Cass will be straight. Although, I'm still hopeful that things would get mixed up a bit this game.
