A handful were pre-ordered but they never took deposits.

From what I remember, a lot of what they had to offer was being surpassed by other companies(and fast). Butterfly labs at the time was working on a smaller miner that would hash nearly 60 Ghs (for only $1299) and they had proof of this unlike Largecoin.

$1299 Butterfly Labs Bitforce SC at 60GH/s

Another major factor at a very large sum of $30k for only 20Gh/s would mean a very un-reasonable ROI at around 600 days or so. It was unfeasible for people who had multiple cards hashing at around 800Mh/s to invest in that kind of miner when they could easily pick up a few more cards. (This on top of cheaper and faster miners.)

Another major issues was the way that it mined. How it would rely on Largecoin infrastructure to make mining possible while others would allow you to do all the setting yourself. This made people like myself scared as how could we be 100% sure that my hashes wouldn't be redirected or hacked even.

Some other companies that were working on the same type Asics during the time.

All and all I do believe they just fell by the waist side and became slightly overwhelmed by competition and even irrelevant in terms of price and hash.
