Sadly, I don’t think we’ll hear anything.
They are fully aware of the situation. People asked about it on their social media channels, on the Steam forums, and here. They answer other questions about the free upgrades for users who can benefit from their promotion, and all sorts of questions (demo issues, …), and skip those from users who bought the whole thing like you and me, and who are unable to benefit from the current promotion.
Like they conveniently ignored all questions about the launch prices on Steam, while replying to others asking about launch times, or disk space needed for the whole package.
I fully expected the game to launch on Steam at full price, so in that sense I paid exactly what I expected to (I even put some funds on the side for 3-4 months, to cover the cost of the game + DLCs).
But, it obviously doesn’t make any sense that those who paid the most, are the ones getting no “reward” at all.
I love IO’s games, I’m a long time follower of their output (even outside of the Hitman games), so I obviously like them, but they really need to improve in a lot of ways. The way this whole trilogy was handled (for example, the whole thing with multiple packages causing all sorts of problems and confusion to users), and the mess that was the current Steam launch, clearly shows they need to step up a bit when it comes to the way they sell their games, and the “relationship” with their customers.
It’s perplexing how they do some things, without anticipating obvious problems and complications.
