I expect they could have. EA is not a small company, and Bioware is pretty damn famous as well. This game had enough hype that it was guaranteed a ton of purchases, regardless of the time of year they released it. But the gaming industry is now driven more by profit and less by the developers who just want to create a fun game. A price to pay I guess, considering gaming NEEDS to be an industry to actually succeed.
As it stands, I don't think the CEO of EA is a gamer (at least in the sense of: rose to be a leader from a lowly position as designer/programmer/writer, what have you) - he's a businessman who has been CEO of companies that don't have anything to do with games in the past. He's not necessarily personally invested in how much people want a high quality product, but rather in profit margins from tons of medium/low quality products (disclaimer: facts taken from his profile on EA's website, opinions formed by ME). And I think that's a shame. A few executives, taking an interest in what their company actually does, might turn the rushed production trend I've seen over the last few years around.
