Thinking the same thang. Seems like they would be awesome but by using these BFL's, how much longer till the last bicoin will be generated?
The difficulty will increase, so it will still follow the same path after the difficulty corrects itself.
To elaborate: a change in network hashing power will not cause a change in the rate of Bitcoin generation. A (roughly) set number of Bitcoins is added to the system per unit time, regardless of network speed. If speed increases, difficulty will increase proportionally.
