@OP, I think we should be more worried if this game is selling extremely well. RPG games in general do not sell very well. Look at The Witcher 2, todate they have sold how many copies? About 2~3 million?
For a game to sell well, it must appeal to the masses, it must be more main steam. The 1st criteria for that imho is make it more action packed, more streamline. Or make it a sandbox RPG like TES where anything goes. The current audience that they have can only sell about 5 million copies. They want more, they have to reach out to those who are not currently fans of the franchise and that means change, changes that could be so extreme that we may not like.
If Bioware tries to appeal to the masses, they will probably do a lot of things that will make some fans furious, they will turn into Rage Demons and set the world ablaze. Actually... some of the changes they made already made a lot of traditionalist furious; "It aint RPG if it does not meet every subjective preference of mine" they cried.
