You should take a look @ chinese maufacturers starting to flood market with dozens of petahashes of hashrate with cheap miners...
this is exactly why Im trying to stay away from the antminer, it LOOKS like a good deal, but I know that huge hashing power is likely to hit soon. this is what is edging me into the preorder area, the hope of beating the chip size. maybe I should just wait a few months though for the dust to settle though. the Chinese will force research and development of better technology if anyone else wants to stay competetive, and that was something i was hoping to help fund in return for a good miner in the future anyways..
Ive heard mixed things about scrypt asics, some people are saying the asics are not worth it to buy a asic because they are not much better than gpu setups, does anyone have any imput on this?
