No offense but the numbers look way too optimistic to me... there is just no way they are going to get 40+BTC on 13GH/s.
I can see "if you are lucky" 25BTC left in the life of these blades, if they start mining tomorrow.
I created a google spreadsheet in my admittedly pessimistic posting:
https://bitcointalk.org/index.php?topic=236050.msg2494899#msg2494899The exponential curve fitted by Wolfram Alpha seemed too low, so I increased the exponential slightly.

Major hash power is coming soon and this spreadsheet doesn't factor in any of it. It just follows the exponential curve based on the block solutions starting in 2013.
In mining it is better to err on the side of pessimistic difficulty than bet on favorable.
Obviously, this exponential growth won't go on forever and I can't predict when it will stop... but I am pretty confident that it will continue to grow for the next 8 to 10 months.
I too am sorry for your loss. If you can get more than 25-30BTC for your blade... consider yourself lucky and jump on it.
