I have to quote again David Gaider for all to see what is it about :
As Gromnir says, there is no alignment, declared or otherwise. If we track how good or evil your actions are, they do not restrict your dialogue choices and if you want to flip-flop between them the only repercussions will come from the choices you make.
As for divergences in the story between weal and woe? Uhh... yeah. Okay, sure
But there are separate ways of responding to events, regarding how you want to act, good or evil :
You mean completely seperate? Like a story for good players and a story for evil players, completely different things? No, of course not. That would be ridiculous.
Are there seperate ways of responding to events, some good or evil, which can lead to consequences and possibly divergences as the story goes on? Well, sure. But what does that tell you? Not much.
But, if there is no alignment, how will DA define morality :
I believe our plan is to keep track of how evil/good you are acting... but that will be a completely invisible mechanic which the story uses as opposed to an attribute of some kind. You will not be racking up "evil points" that you can see or which would affect your character outside of the story, and at no point do you select your "alignment". Reputation is something different, and depends solely on your public actions in the course of the story.
It seems that will be implemented a feature similar to virtue. Reputation and morality won't be the same thing anymore.
