They don't care...They know that miners NEED the latest and greatest. They also already have your preorder money. They know you lose $$$ everyday you have to wait to get it back from them under an RMA. They know that they can simply offer you 2% off your next order (which is likely to occur about a week after you finally get your miner back from them, as that is when they'll be pre-releasing their doubled/tripled hash rate models)...
Its a vicious cycle...and we (the small time miners) are in the wash...
