Don't be silly. Why on earth would Bio write such a game? It's not like the Wardens are going to accomplish something like that without the writers making it happen.
Oh no, let me clarify. The wardens will be bathing in the blood of archdemons and magister, the inquisitor is the one who'll be having tea with the empress while the wardens are knee deep in blood. The inquisitor is now a wealthy politician with an army, almost a king. The warden is still a soldier.
I want to see some inqisition dlc, but they wrote themselves into a corner with the inquisitor, he's so powerful he can't be a PC again unless they put him in a completely different land (and they can do that with the warden as well, who has more history with the major plotlines).
You know, we could find out about all of these things without our Warden. The warden is not some superspecialawesome magical key to unlocking these mysteries... Another protagonist could do it as well. If you need a warden... well, our warden is hardly the only one left.
As for the whole old god baby...
That said, I don't ever want to play as the warden ever again. I wouldn't be opposed to the warden joining the Inquisitor or future PC as an NPC like Hawke though. I don't trust them to get it right because of the simple fact that when you play, you add a lot of headcanon justifications and reasonings. They couldn't even get it right in the Awakening epilogue slides where my Warden apparently left the GW to frolic around with Zevran... my Warden took her duty as Warden-Comander very seriously and wouldn't leave her post like that.
Given how intensely attached many people are to their warden, even if they could bring back the warden it would most likely not be worth it because of the inevitable backlash. Also, they're never going to invest in the amount of VA people seem to want for it to work. VA work is expensive.
The local wardens really crapped the bed, they need a hero... and true, there's a lot of thought into what made our wardens who they are, but it was also 10 years ago, even in our heads they'll be a little different now. And inquisition does pretty well with four voices, I could live with that, the warden never had anything but one liners for swinging his sword and moving in DAO anyway. My warden went adventuring with zevran as well, but that was after ameranthine, it's not like she quit, it's also just something some people were saying she might have done, if i recall correctly.
Not everybody is going to agree, but the idea of updating my warden 10 years into an older and wiser soldier from the kids they started out as really appeals to me.
And a new PC is always an option, just if a hero is imported, there'd be different dialogue and fewer introductions. I REALLY want to see him encounter leliana, my warden currently in the keep killed her at the urn of sacred ashes, and she had a lot to say about that in inquisition... it'd be very, very tense. He also stabbed morrigan who he romanced when she abandoned him before the final battle for turning down the ritual... no new PC can live out the impact of those things.
I think bioware can do it, and the story will be that much richer just to have the option of using the HoF.
We did get a true Qunari. The IB has a crisis of faith when the Qunari set up with a Sophie's choice loyalty test, but otherwise he generally embodies all of their beliefs.
I like Iron bull, but he has zero in common with sten and the arishok and every other qunari we've ever seen. They're stoic and blunt, maybe IB has been in ferelden too long, who knows, but he acts like a human. I want to see some qunari kind of like sten, dedicated to their job and nothing else, stoic and awesome.
Plus, why do qunari all have human eyes now, in DA2 they had the black eyes with white irises, really bummed we can't have those and make a qunari who doesn't look like a human with horns... plus now qunari seem to have one horn on each side, look at the ones in Da2, most have 2 or even 3. And you can't make something half as impressive as the arishok in the CC.
The new qunari are very "pretty". Here's hoping the new krogan in ME4 won't be based off supermodels...
