I'm on the fence. I never really bond with a love interest until I've spent about twenty hours badgering wandering about with them, poking and prodding them, exhausting all dialogue options, (and possibly party banter) before I inevitably decide whether or not I was satisfied. So, I have no idea and since my batting average hasn't been really great with the romance predictions so far... No for Varric (more of a vague hope), no for Viv, yes for Solas... I'm just hanging back, I don't even have any romances planned other than being curious almost all of them.
I have my doubts over whether or not Iron Bull will be for me. On the one hand, I love interspecies romance. I've wanted to romance a qunari since DA:O and his personality seems to be shaping up to be the sort of work husband/work wife, bromance/romance my Fem!Shep enjoyed with Garrus (though obviously only in spirit, very different these two) with a little more Izzy style boinking. The Kill Things Couple, on date night they go out and hunt mercs (though that could easily wind up being Blackwall). On the other hand, my version of qunari is more Sten and the Arishok. Iron Bull feels more like Tallis to me and since I didn't particularly care for Tallis, meh. Then again, Freddie Prinz Jr. makes up for a lot. Like a lot.
I'm going to need time for them to grow on me. I didn't like Isabella originally, and lost her on my first playthrough. Turns out, I honestly sort of, kinda love her. Didn't care for Fenris until I realized how funny he was. Really. He's my most romanced character of DA2.
I didn't like Zevran, but I kinda like him now. Same with Morrigan. Here's hoping we get no more Anders surprises. 
Still, there are some characters I just can't warm up to as romances. Merril. Leliana. Sebastian (I know, Paul Atreides... I just can't do it). Thane. Jacob. Jack. Ashley. They're just not for me and if they were my only options, I know I'd feel pretty lousy. So, my sincerest condolences to those who were hoping for a different outcome and didn't end up with the LIs they wanted. It really, honestly sucks. Feeling like I'm not the preferred customer base in a space where I originally felt safe and comfortable is the worst. I can only imagine what it might be like those far more invested in this than I am.
