Yes, The Odd Gentlemen are a small company - but they have the financial backing of a much larger company, Activision. The money Activision has to spend on promotion and advertising for this game would make a Rockefeller blush.

I somehow seriously doubt they got the same funding as an average Call of Duty game. Nor do I think they have anything to match the Rockefeller's legacy...
So far this game has mostly been advertised on world of mouth, free facebook message board, the Odd Genteman's website, and a very cheap "Sierra" website.
If you read the behind the scenes stuff for the Gabriel Knight remake it doesn't sound like Activision gave Jane Jenson and POS much of a budget for that game either... It shows in many places (as it many animations are completely removed and animation is more static, puzzles simplified to remove the need for animation in places).
In that Adventure Gamer article I noticed the part where it mentions there is to be some villain that is tied into the entire series. It looks like it will probably be the Sorcerer who enslaved the dragon back in KQ1, and stole the mirror.
My personal guess is that sorcerer's identity will be revealed to be Shadrack (and "finally" tie up that one "loose end"). Unfortunately that also borders on 'over used' fan plot line #1 (as every fan author and every fan game has basically tied Shadrack and Black Cloaks to most of the KQ stories in someway)...
