Combat lore quibbles are about the last thing on my mind when I ponder the RPGs I love, but I recognize that a large portion of the core fandom it's kind of a big deal. To that end, I'd call this marketing maneuver a bust. Still no real depth unveiled in the mechanics themselves, too, which is another of those things I don't think will end up mattering much to me but is highly important to, well, a lot of people. So for their sake it'd be really great to actually see some of that in this last two months, but for whatever reason it's looking unlikely.
The marketing for this game has been, frankly, terrible.
First there was the whole romance announcement debacle. They should be all up front about who were love interests, who were not or just not talk about it at all.
Then there is the "8 abilities locked across all platforms for combat" and they have not, to this date, made it clear to us why they chose this particular design philosophy. All we have heard are stuff like "There are 32 abilities for you and that's enough" or some PR lines as opposed to an interview with the gameplay designers explaining things and relieving the concerns we mostly have with this approach which primarily involve repeated button mashing for long boss fights or wave fights.
There is also the Keep customization, not DA:Keep but the Keeps in the game. People have been clamoring for more information on that for ages and absolutely no response.
If you want more, there is the Vallaslin debacle. They made it mandatory which is great because it is Dalish and Dalish that are of age have Vallaslin. However, they have brushed off the idea of explaining what each Vallaslin does even though by lore they have it written down that each Vallaslin represents an Elven deity. They could at least make a blog post on Bioware Blog or a post in Dragonage.com or have someone like Gaider post stuff on his Tumblr account because this is lore stuff.
Finally, there is the combat abilities. There are threads that have constant speculation about them, there have been people who have been eager to see the skill trees and all we have heard so far is "there will be over 200 spells and abilities" and now "here's a pretty picture with 3 freaking talents". There's also the combat gameplay video series which has of to date, only had one video.
