I'm a bit baffled at the some of the responses I've seen here. I realize that this is something of a community project, and that people feel like they deserve to be "in the loop," but if you haven't sent Spyderco any money, they don't really owe you anything...
The initial list was, as has been mentioned over and over again, an effort to find out whether the interest expressed in the forums was genuine. Spyderco went out on a limb and trusted that we were going to buy these blades as we said we would, and it's now up to us to prove that their trust is well-placed.
If Spyderco had asked us all to pay up-front to fund this project, things would have worked out differently--and I doubt that the project would have been very successful. Hopefully, the way things are, we'll all get to play with the neat-o steels, Spyderco will gain some useful feedback on the steels (not to mention brand loyalty), and everyone will come out ahead of the game.
(Then again, I only heard about this project last fall, so what do I know...)
