The plan of the company has been unveiled by BioWare’s Greg Zeschuk during an MTV interview:

"With Dragon Age, our DLC strategy is doing it in maybe a year and-a-half or two years, planning exactly when you’re going to do it and how you’re going to do it. Some of our fans would really like us to extend the world, so it’s going to be something that will make the world even bigger and more interesting. It’s not going to wreck it or break it."

Leeaving the PR talk aside, this comes down to either BioWare working hard on good updates (the good scenario) or the same BioWare will take a digital pair of scissors and will cut the game way too short. So they’ll have enough content to add later.

You may keep your hoping the second scenario will be proved wrong. Then again, do remember that BioWare is now part of Electronic Arts. And everyone knows how EA operates…
