I can't answer that and nether can you with exact to the right numbers and dates. Thus your guess or generaliztion is inaccurate. What I do know is enough orders have been filled to satisfy me.
I will agree that preordering from such a small company is a big risk.
My generalization is inaccurate? Tell that to the list of people that haven't received their orders yet. I know that isn't everyone, but how likely is it that everyone but the people that have listed their order info on the list have received their hardware? I think its far more likely that things just aren't shipping.
Presumably, the money is being saved up to start the asic process which will have to be spent in one large chunk. After that hurdle, new money for orders will go towards filling the old orders.
