User blog comment:Dr.Xen/New Content Hinted? (Possible Spoiler!)/@comment-13691566-20130818003440

I'm tipping that they will progressively release new content for DX:TF, and let us unlock it by paying for it.

If they do that, I probably won't bother; the price of DX:TF was too high for the length of the game, and cranking the price up surreptitiously by forcing us to pay for the next installment doesn't sit well with me. I'd be less annoyed if they made it clear in the description that it only includes a small chunk of story.

If, on the other hand, the next installment gets released to purchasers at no charge, I'll be more kindly inclined towards them.

We shall see...
