Ahemm sorry, but I really think you should take the huge differences between Larian/DTP and Bioware into account
Bioware is an internationally acclaimed trademark and well known in every important market. Every game from them WILL result in a hype, regardless of its actual quality, actual known facts, the price etc.
It's just the name that makes the hype.
But Larian is obviously very different. They are much smaller (in terms of financial capabilities) and they are by far not that known in the world.
So, the marketing and hype around Bioware is not at all comparable to Larian's situation.
Furthermore, I think (not sure) that marketing is organized by the publisher. So DTP is to blame, if you think that the game's marketing strategy is flawed
