I did a small projection of FPGA farm mining with the rise in difficulty level. Not entirely accurate but it's based off of projections and current USD/BTC, etc.

I did not find one spot where you mentioned anything about difficulty.

The difficulty rise is in the charts. I estimated a large purchase of FPGAs based off of an old estimation of the rise of difficulty, showing that the rise in difficulty level will make a ~48GH/s almost unprofitable.
