Amnesia: The Dark Descent -NA Retail Box Relese?

[Frontcannon]

And whoever said that Frictional Games won't be able to publish physical copies of Amnesia because they're an independent developer, how'd I get the Penumbra Collection then?

The Penumbra games were published by Paradox Interactive, I think. When they screwed Frictional over, they went independent for developing Amnesia which is the reason there is no retail release and most likely never will be.
