I am sorry...but no.  AsicMiner had many statements with the word, "exahash" thrown around and even the earliest Asic manufacturer couldn't get anywhere near that level.  Not to mention they are already showing delays and instead of having a new deadline are saying it is a competitive advantage to not tell anyone.  Reading through that article I was met with one red flag after another.  Maybe not a scam per se, but they are way to ambitious and will likely fall very very short of whatever goals they have set.

Take Bitfury for example, the largest self mining company who has spent millions in data centers and development of the most efficient miners, probably is still under 100 Petahash, and this company says that they have orders for 20X that amount, I highly doubt it.
