I doubt bioware would leave out companion romances for het females. Only having an npc would be way unfair. Also, only having iron bull as a romance option is also cruel. I play for the romances. Why add 8 romances and only one companion for het girls?
There's still slots left and Patrick is writing a romance and I doubt his romance tweets are about iron bull.
Im almost positive Solas is an LI. Bioware wouldn't forget us like that.
So cheer up people! We still have 2 slots left!
Also Allen is sooo trolling with that "don't want to be cruel" comment to throw us off I bet. Lol! He's sneaky that way. 
P.s I do hope they reveal LIs soon because I'm running out of time to pre-order. Yeah, I'm one of those. 
I don't want to get you down, but I really need to address some of this...
Why would only having Iron Bull be cruel? Sure, I don't find him attractive and his described personality is definitely not my thing. But, there are plenty of people who think he's just amazing and hot and fantastic. So no, it wouldn't be cruel, just not to the tastes of some people in this thread.
There is also no indication that things will be equal. Many women begged and pleaded for Cullen, so now that he is in-game, it may be that the writers and developers felt that women would already be happy with what they had. I do not personally want Cullen--he's hot, but his anti-mage attitude means most of my characters will not like him. I would prefer if straight women could have a companion romance, other than Iron Bull, and I am sure we will--it will be among Varric, Blackwall, or Solas. I wouldn't expect this character to be straight, but rather bisexual. We may even get two of those three, though it is doubtful.
Iron Bull is confirmed as a romance. Why would Patrick Weekes's romance tweets not be about Iron Bull, who is confirmed as a romance?
Allan is coming in probably because he's noticed how up-and-down this thread is. He isn't allowed to reveal anything, though he may know when the next reveal is planned. Romances do not actually matter that much to him; he's said so repeatedly. He could be feeling bad for us because we won't get Solas as an LI and he knows we really want that. Or he could be trying to keep our hopes up because we will. We won't know until after the fact. I wouldn't read too much into his posts or his presence. He's in the QA department and, even if he wanted to, he is not allowed to tell us one way or another. That will most likely be handled by a writer.
Now all that said, I'm not trying to bring anybody down. Your post is right in one thing: There are two spots left. Most likely Vivienne is one of them. The other, I think will be either Varric or, less likely, Solas. But we may all be surprised and it could be Blackwall.
I just wish Weekes would reveal something so that we could all move on.
