Nope.
First, I posted that before you'd clarified the state of the development, or at least before I read it.
Second, it's an old, old, programming joke, not aimed at you personally. It states that the presence of video of a functioning system is not proof of the existence of a functioning system. (If you have never read about Microsoft's Windows 1.0 demo/announcement, do so. It's a riot.)
Third, I generally assume no representative of a corporation would be stupid enough to out-and-out lie in a public forum. If you say the system is almost good to go and will be live on June 6, I accept that is the truth as you currently see it. I may personally have trouble reconciling this with statements that the program was in alpha not very long ago (around December-January, IIRC), but you may have the most kick-ass dev team on the planet working for you. We'll see how it goes. My skepticism is based on the fact almost no software EVER ships on-time and feature-complete, and this is a pretty complex piece of software. If you pull it off, your coders and testers deserve the highest praise (and some nice bonus checks).
