I am sure we will see Solas soon, just not next, judging from the current trend.
As for haters, I am sure we will hear from them and then they will eventually move on to something else to hate. The trick is to not take it personally, I suppose and not allow their negativity to interfere with something that brings us (well, me since I can't speak for anyone but) gleeful joy. Though I hope no one will think too badly of me if Solas is ever confirmed as a romance, if I do a happy dance with a touch of gloating for all of those who are dismissing him as unimportant at this time 
Seriously, I think the romance numbers are going to surprise us in a good way. And I don't think they are going to reveal some of the hidden ones, instead leaving the players to stumble across, like ME2 did with Garrus. (Yes, when the game first came out, no one realize you could sleep with him until someone discovered it. I could check but I don't think he is even listed in the walk through guide book I have.)
