Unlikely you say?
Why do so many people on the forum think this is unlikely? Is it just because Dragon Age has always had a new protagonist before? Is it because that one vague statement about Dragon Age being about Thedas not any particular protagonist? Or, is it just that a lot of people on the forum like the new game=new hero thing and don't want it to change? If I hadn't heard any of this new game=new hero stuff online, Trespasser would have left me 100% certain the Inquisitor or ex-Inquisitor is coming back.
Weekes has said he intended for Trespasser to convey that there will be Solavellan closure in the future (as long as there is another game). I don't think he's cruel enough to consider a new pc asking Solas about his girlfriend or a war table mission closure. Trespasser only makes our Inquisitors more relevant in the story that is yet to come. It makes the "fight" with Solas personal. If we don't see the Inquisitor as a playable character for at least part of DA4 I will be extremely surprised.
People on other parts of the forum bring up the arm all time as evidence of new game=new protagonist. The missing arm is no excuse to toss out the Inquisitor as the protagonist. Losing the arm was the only way to ensure he/she would be alive to remain the protagonist. It provides Bioware with a believable way to reset the player's skill trees (like Shepard dying at the beginning of Mass Effect 2). If they took the Quizzy's arm just to make it "impossible" for her/him to be the hero that would be a pretty ugly and totally politically incorrect move on Bioware's part.
I think we have every reason to believe our Lavellans will meet Solas in a future game. Team Optimism!
I have to say, I have pretty much the same line of thinking. Going into Trespasser, I was thinking they will end the story of the Inquisitor, but they have left it so open ended, that I can help my let my mind wonder if they will keep the same protagonist for DA4. It has all the pros that you are talking about
- seems like ex-quisitor is still relevant and has fight in her/him left
- story seems to not be completely resolved and very tight around hunt/redeem Solas plot
- lost arm seems like a prefect chance to wipe off all the skills/powers and start new (BTW, having disabled protagonist would be absolutely AWESOME in my books, just thinking of the cool weapons and gadgets that could be attached to her/his arm make me really excited)
BUT there are also many cons that are just as strong
- What about new players who don't know inquisitor and their story (yeah, I guess they could be caught up via-DA keep... but how many people will know about the keep? I only learnt about it (properly) after completing the game)
- What about romances, especially for non-solasmancers? Surely it won't be easy, again for new players, to continue romancing the same character (say Cullen) from DAI who they know nothing about?
- and finally 'It is a story about Thedas and not about any particular character' bit
I am sure there other pros/cons (I am also sure, people have discussed this before, sorry guys, catching up with the thread as been away), but these are the main ones going through my head. So I am still undecided of what is the likeliest outcome for DA4 protagonist... so I guess, yay Team Optimism?
