I'm sure we can patiently wait, they're doing us a huge favour which I for one, am very grateful for :)
I hope the last comment about being grateful didn't come off as arrogant, I just think its fantastic when people release information like this as this is valuable in its own right, but also a good starting point for people trying to get a handle on the startup business.
Top work YC!
