We all predicted the "unknown" asic companies secretly developing...and here they are... now you chastise the secret development, when it's a key component to any high tech business?
at a time when a vast majority of asic buyers have been burnt in some way or another with pre-orders, any new company who want to sell cutting-edge stuff would do better rolling out when they are actually mass produced. I don't think it's a fault of any company, but previous experience will make us all stop and think twice. It's not unreasonable to want to see physical proof (rather than sexy renders) of new rigging.
