Someone who understands this more...please comment.

If the current BitCoin network is 20.6 TH/S @ 2.86M difficulty, what happens with BFL ships their 10k orders of ASIC miners at 0.06TH/S each order on average.

This would effectively add 600 TH/s to the network?

According to straight multiplication calculation...this means difficulty of just under 100M. This would make the payback over 1 year instantly...not good.
