So if the "chinese cyborg" is an arm of the gridseed manufacturer, then I wonder if they one day they might look back and realize that it really was not the most profitable move to significantly depress the value of scrypt coins before selling their hardware to customers!  It's only been two months since their appearance, but now they will have fewer buyers at the prices they desire, as the coins themselves are only worth half as much.  I know that I'm certainly not going to buy any single purpose hardware that becomes completely useless when the coin markets move on to the next algorithm.
