Well, to be honest, what else can they do? Hope it succeeds, but then BioWare decides to ignore this success and go back to the financially less successful design?
There is no excuse for posting that you want the game to fail in a nasty, mean-spirited way, but...I did kind of hope Inquisition didn't do well. Like you, I think the side quests are very boring. Perhaps unlike you, I think they actually suck the soul out of the game. I feel like I don't get nearly enough circumstances with which to characterize my Inquisitor, and that was the best part about BioWare games for me.
My favorite parts of Origins are the little things you get to decide during side quests. Feed the prisoner. Keep the sword for yourself. Spare the man who betrayed your family. These minutiae are what make up who a character is, in my opinion, strangely more so then the big, world-altering decisions you get to make in both games.
But with this success is going to come positive reinforcement. With positive reinforcement, there is little reason to change the formula. I can't force myself to like a game. So am I just done with BioWare games now? That would be sad. Imagine if the opposite was true. I'm sure you all would be sad as well. I know I wouldn't revel in your misfortune.
The reason i like the little stuff is because ypu get to see the immediate result. With the big choices the results are typically vague because they have to be made into a running story, that has to account for the results. If you beat up a peasant and steal his family heirloom, it has no affect on the over all story so you can see the beginning and the end of you actions. And you dont end up feeling cheating because someone 'likely' will die, or the person you save disappears in the next scene anyway.
