While a part of me wants to know which DA:I characters will have which orientations, one of the most pleasant surprises for me during my first playthrough of DA:O was finding that Alistair was romanceable, which only really dawned on me when he said something totally swoonworthy to my Warden on arrival at Redcliffe. (I bought DA:O a while after release, not having particularly followed development of it, because I had little interest in gaming outside of playing and modding NWN at the time.) There's something really pleasant about being surprised in this way. As such, the time for me to step back a bit from development news might be soon. Maybe I can avoid too much info about companions before I get to play DA:I for the first time.
Before I do, though, I have a few more thoughts on this subject. The linked quote mentions that DA:I romances will be more complex. This notion interests me. I hope that it means that there will be more differences between the various romances, that individual romanceable characters will want and offer different things.
In the NWN module that I've been working on for a very long time, I've tried to put a lot of variety into the romances, and this isn't just at the level of orientation. Following the lead of Andarian's Sanctum of the Archmage series, I made the actual gender of some characters different based on one's version of the module. (I would have been very dubious of this before playing Andarian's module, but he really won me over. These characters' personalities, backgrounds and motivations were ultimately more important than whether they were male or female, although being male or female did introduce small variations here and there.) Some of my romanceable characters want open relationships, some are happy to take things as they come without worrying about the future, others want monogamy without marriage, and still others want marriage and won't sleep with the protagonist until married. Some romanceable characters will also be more or less committed to certain factions, alignments, and ways of life. How the romance will go will, naturally, depend partially on what the player character wants from a relationship, their faction alignment, their views on how to achieve objectives, etc. Some characters will be willing to forego some of their own requirements or desires if that's what it takes to be with the PC, while others won't bend.
Anyway, I mention all this because I'd be interested to see something like this in DA:I, and I wonder if this talk of complexity might presage similar things. In absolute fairness, it is hard to add so many variables. It is a part of why my module is not finished yet. Good old feature creep!
Nonetheless, I do wonder if some romanceable DA:I characters might not be willing to form a romantic relationship with an Inquisitor who has very different values from them or wants something very different from life. Alternatively, there might be a special attraction for some when the Inquisitor is very different to what they're accustomed to. For some, maybe, a fling during the current conflict might be fine regardless, but in the long term they might feel differently, etc.
In any case, time will tell - and, with any luck, I'll be able to avoid most of the info related to the topic I've just discussed, and be surprised by my first playthrough.
