Just seems a little backwards to me. IMHO, it should be Developers bring out the Demo, not the Demo brings out the developers. I think the point that everyone is trying to make is that 2 years is a long time. And doubly so for "amatuers" working on it as a hobby.

Don't get me wrong, I wish nothing but success, but as a person who has gone through numerous changes in a short time span, I've come to realize that in 2 years time, alot can happen with team members, be it marriage, kids, employment, and (god forbid) death.
