The main ME studio was working on Anthem, and Andromeda was outsourced to a new studio in Texas that previously developed DLC for ME3. Half of the DA team was/ is working on Anthem along with their main studio. When Andromeda didn't do well they closed the Texas studio and moved remaining staff to work on Anthem. At one point last year EA openly said all of this, so basically the entire studio bar a few core Dragon Age members were working on Anthem.
They'll be entering crunch with that now so while we know they've entered full development with the next DA I find it unlikely the studio will last much longer unless Anthem is a major hit. If Anthem tanks they'll probably finish up the next Dragon Age then close up shop, if even that happens. They've already completely shelved Mass Effect.
Into the bargain they can't get away with old Bioware style tactics - meaning buggy messes. Granted Andromeda was slightly worse for this than Bioware's usual fare but Dragon Age has been notoriously buggy. I would take Inquisition again in a different setting in a heartbeat, but the larger gaming population will not. The cries of "but The Witcher 3" began only months after Inquisition's release, and the relative fanfare Inquisition got was mainly because it was early in the generation and everyone was starved for a decent western RPG (as much as I think it's amazing - it's probably still my favourite game of this generation).
Summary of factors:
- Bioware studios consolidated to work on Anthem, skeleton team left for DA
- Mass Effect IP mismanaged, Andromeda was buggy and poor in some major gameplay aspects even though it had 5 years of dev time (but only 2 in actual development, again due to mismanagement)
- Mass Effect IP shelved by EA
- Inquisition The Return would rate poorly among gamers and critics alike because other RPG's like The Witcher changed the landscape for what is and isn't acceptable from a progression standpoint (no MMO-style quests as padding)
- They're being forced to use Frostbite for everything because EA demand it, and they've had notorious trouble getting key RPG systems to work in it because it was invented for Battlefront
- EA is focusing - like other publishers - on "games as a service", which is not a model that fits with Bioware's single player IP's in general. They've already announced they shifted gears in development of the next DA to accommodate this
- Anthem is EA's "we want the Destiny market" ploy but the Destiny market is kind of dying
Bioware is in major trouble - not just because of EA, but also because of their own mismanagement.
Mass Effect was probably my favourite franchise of the last generation and it was hugely popular. It's insane how quickly it was killed. I don't want the same for Dragon Age, but it's hard to be optimistic. I hope my fears are wrong.
