I really don't get people's anger towards post like this. I get its annoying to see them pop up often, but ignoring the posts might be a better option than leaving angry comments.
As for the idea, personally I would like to either play the inquisitor again or dual, the reason for that is that I would like to save Solas as my inquisitor. Saving him on a new character makes no sense to me, as we had an option to "redeem" or "kill him" in Trespasser, doing that on a new character would feel rather odd, having someone else do your promise to Solas.
Plus, I romanced him in one play-through and I would very much like to beat some sense into that egg head, lol.
As for the arm debate, it makes sense Bioware gets rid of it as a way of saying "No arm = not playable" but in some people's play-through Leliana dies in DA:O, but for some reason gets resurrected with little to no explanation as to why. So, if Bioware is willing to resurrect characters, I am sure they can come up with a reason as to why the inquisitor suddenly has an arm, be it magic or the anchor returning for some reason.
It all depends on how Bioware will processed with this, they might not even make anymore, tho if that is the case I believe they would need to fortify their office as angry fans are in-coming, lol.
Truth be told, from what I can read of the interviews from the developers and in-game options. Solas will make an appearance in the next game, should they make a new one. However, Mike Laidlaw said in an interview that "with Dragon Age, we’ve always been committed to providing an experience that has chapters, with new protagonists and news stories being told, because we see it as a series about a time and a place rather than an individual character." That sentence is what makes me think that we will not play our inquisitor, if we did, it would be the first time Dragon Age features the same playable character in two games, which I don't think they will break away from. Dual is possible tho.
I keep wondering why they don't make an expansion pack with this story. Sounds like they got all they need in order to make one and the story would be big enough to fill it out. It would solve most problems they are facing now. We get to deal with egg head with our inquisitor and Bioware doesn't have to worry about whenever they should let us play as a character we already have in their next game.
Guess we just have to wait and see.
