The original Shipment of G4 got delayed due to some production issues that needed to be sorted out. The main is due to the logos being in correct on the receivers. Rather than sell the G4 with in correct/flawed receivers we had the manufacturer make the necessary corrections. Originally the changes were not suppose to effect the production schedule however any time there are issues it takes time to correct them. This is the main cause of the delay.
The reason behind the pre-orders is to be among the first to receive you product when they come back in stock.
All pre orders get built first before the regular orders. With the amount of order we have the first 5 days our technicians will be building the pre orders first. Currently we do not have the parts to build complete G4's in stock which is why we have not processed your order. The parts will have to come in first before we can hold them and set them aside for pre-orders.
