I'm not sure if Bioware succeeded in getting the Call of Duty audience, or the Farmville audience, but I do know that there's a few (or many?) gamers that play adventure games (like Syberia, Monkey Island, Black Mirror etc.) that really likes DA2. Probably because the gameplay feels a lot similar to an adventure game, the story is centered around a person, just in an adventure game (or in story-driven adventure games).
As for getting, or wanting to get the CoD audience, Fernando Melo (and Laidlaw, too, I think) did say Bioware 'wanted to attract the call of duty crowd, the players that play farmville. Interview with Now Gamer as source:

Personally, after playing the demo, I like the changes. Even the changes in combat, (except for the fact that the tactics screen and the tactics gameplay were sort of -ahem- almost broken in the demo; but I liked it nonetheless) I liked. I don't like rogues are now nijas, jumping into backstabbing positions (what happened to the idea of silently sneaking?) and that reinforcements now appear out of thin air. (witcher 1 have reinforcements coming out of the ground...an idea for dlc, expansion and the next game, perhaps...)
After playing Witch Hunt after I've played the demo, I can say that the combat in the demo was way more responsive than the combat in Witch Hunt (and in DA:O). And that the horrible, imo, implementation of the isometric camera, is gone in the demo for DA2, and in the game. As long as I can rightclick and spin the camera around, I'm happy
As for getting the CoD crowd, I understand the reason behind this. I also understand the reason why Varric's enhanced story serves as a tutorial for the combat in the game, and then the real game starts, both in terms of story, character development and combat. I'm not sure that people who normally play action games for the action won't be playing DA2. Note that I'm not bashing people who play CoD as I too play CoD from time to time when I want to play a good shooter game that also has a sort of story, although thinly veiled, I'll admit. The point is that if I want to play an action game, a good FPS game, I play CoD; when I want to play a good rpg with a good stiory, I play a Bioware game.
Many people who play CoD (only) play CoD becauise of the action, the combat, and 'to shoot' things.
I'm not sure making a hybrid game that both has more responsive faster combat and a story with dialogue, character interaction, character development (for Hawke at least) is a good idea to get the CoD crowd to play RPG games. And while upgrading weapons in CoD could be seen as an rpg mechanic - in CoD upgrading the weapons means that you get better at killing things. Upgrading weapons and armours in an rpg does not necessarily mean this, also weapons and armours in rpgs usually have requirements you need to fullfill in order to wear and use them...
My best bet is that many people that play CoD will play this game for the combat, then maybe at some point when the dialogue and character interaction kick in, quit the game. This bet, is of course, just, imo, as always. Bioware's data might show something completely different...
