You're right Statyk, in the Q&A Dan was asked about another Amnesia sequel and
this was his answer:

It's probably safe to assume this goes for DLC/add-ons too. Frictional probably wouldn't have the time to do it themselves because of the
Super Secret Project, which is their primary focus. It was this secret project and its de
mands on the team's time which made it desirable to bring in The Chinese Room to develop AAMFP in the first place. Unless they commission
another third-party team to make some DLC I doubt it'll happen. Although it would sure be interesting if they did!
