On AM value assuming $0.8 per ghs profit; at 200 PH production = 0.6 Btc per share. Anything more, we will be in Btc heaven.
If we're extrapolating: 1600 PH/s production at a profit of $0.80 per GH/s gives approximately XBT 4.8 per share. Not bad, huh?
If we're really looking at $0.8 profit per GH/s, we have to consider that this is only the price for the first month(s). The price for following batches will be lower, since mining will become less profitable. So only the first, say, 50 PH/s will make $0.8 per GH/s, afterwards we have to settle for less. That being said, it's not completely unreasonable to expect another 0.6 BTC per share coming from gen 3. Which would (still) be perfectly fine in my books...
