I would love to see a game with a similar scope and scale as DA2, only with more polish and fewer rush-jobs. But it's extremely unlikely we'll get that. It's not about what BioWare want to make, but about what EA want to release. And between the backlash against DA2 and the current look of the industry, another open world, large-scale game is looking much more probable. Unless the backlash against Andromeda made it swing the other way, but I doubt it.
