Yep and it has been shown that where there is profit corporate miners will blow up the difficulty, leaving home miners in the dust.
Pre-Ordering anything is a sucker bet at this point, if it were ever anything else, as is the majority of hardware, unfortunately.
No money in mining anymore, IMO. Do it for fun, fine, but nobody should expect to make any sort of money whatsoever.
If I had my choice I'd go back to mining with graphics cards. There was something fun about building your own rig and messing with it. that was a hobby at least, you didn't have to drop a bazillion dollars to do it and at least were left with a kick ass gaming computer at the end of the day.
