On the Zetheron website, the breakdown of which algorithms are viable combined with how many FPGA's they can support is intentionally deceptive to throw other companies and developers off the trail.  While some parts of the table were accurate, I left out several of the biggest and most profitable coins and some of the 'supported # of FPGA' numbers were lowballed to make them look unattractive to other developers.  In addition, many up and coming coins that didn't even exist in April have algorithms that are FPGA viable so the total pool of coins that can be mined by FPGA's is increasing, rather than decreasing.
