The problem with the next generation of chips is the rapidly declining benefit to mining. They will come on line in production quantities and will see the next halving during the projected useful life.
If the supply of new bitcoins is halved shouldn't the price increase to reflect that?
Agreed, this model of selling hardware to consumers cannot continue for long. You're lucky if you can obtain a ROI within a few months, as difficulty skyrockets, power requirements for the miners go up (not down), and the price of electricity always haunting you, there's little room for profits now. The hardware manufacturers act like they do us a favor when they pre-mine on hardware that we paid for, ship late, and then act put out when we start asking questions. Frustrating to be a miner these days...
That's why you shouldn't pre-order.
