To start with, I don't see any reason for why 2k and Gearbox has earned preorders for this game.
They took a deal to sell the game on an inferior store with an inferior client, with Denuvo added on top of that. And then they have limited the sites that will have reviews up at release.
Why should we reward any of this with giving them our money before the actual release, before actual reviews and impressions of the final product?
The game is definitely so low down on my priority list, with how they're handling the release of this, that the Steam version will most likely be out already, before I can even contemplate to give them money for this.
