I ran some numbers for fun, excluding possible profits form mining

Total Profit: 4667689.416
This is total of 4172 units. Because nothing will happen before December, they have about 37 weeks to sell it all.
To produce 112.756 units per week is probably no big deal but can you actually sell all that hardware? This is 112.76 units every week, nonstop.
BTW, this is about 550 Thash of mining power. The whole network today is ticking at 692.909 Thash/s.
Margin Formulas/Calculations:
The gross profit P is the difference between the cost to make a product C and the selling price or revenue R.
P = R - C
The mark up percentage M is the profit P divided by the cost C to make the product.
M = P / C = ( R - C ) / C
The gross margin percentage G is the profit P divided by the selling price or revenue R.
G = P / R = ( R - C ) / R
EDIT: Some say that $1.50 per Gh is about right expense. It is hard to believe but updated calculations are here
