If said games aren't rushed I would welcome one Bioware game per year.
The last few games have been slightly disappointing to name some issues:
1: DA2 - Reused environments, dodgy wave mechanics (magically appearing enemies....I mean come on some appear floating in mid air then drop down!!), etc
2: ME3 - Ending, Fetch Quests,...........Kai Leng, Galaxy at War, etc
They are still great games by any standard and I still play them, however as Bioware games they were not up to the standard I would usually expect.
From what I've seen of Dragon Age Inquisition it looks like its shaping up to be an incredible game and if Bioware could ship one game every year with the same quality and care as they look to have given DAI I would be ecstatic.
I'm not really that bothered about Bioware moving away from the old school rpg's in favour of a more mainstream audience as long as the same care and dedication is shown in the new games.
I have found in recent years that the sort of games I can enjoy has decreased immensely as the graphics have improved.
I got into gaming as a kid with the Sega Mastersystem 2 playing games like Alex the kid, a weird game called Robocod and Sonic.
For years however my go to games were the Final Fantasy series, Command and Conquer series, Croc, Crash Bandicoot, Zelda the list goes on.
Now however the list of games I genuinely enjoy and replay is only around 15 or so and half of those are Bioware games.
I'll end by saying if Bioware could to the best of their ability release a game every year without rushing or cutting corners I would be the first in line. I would think that four or five studios would be needed to ensure an appropriate development time is given to each studio.
