What exactly prompted you to upgrade Bitmain's pre-order status anyways?  The L1 pre-order is still part of this current generation, and they haven't released a new generation.

And I agree with SP-tech.  They claim to sell next gen out of hand.  If they even allude to changing this strategy and offering pre-orders, you can go ahead and down-grade on the spot.  Why is Bitmain getting preferential treatment in this pre-order category?
