We've always known that our chips are overclockable from 16 gh/s to 20 gh/s.
I'm reading that Intelihash will bring something extra to the party. A 20% one off over clock isn't the 'game changer' that is being implied imo.
Remember Ken said we knew we were unlikely to make ROI months ago, and went back to R&D so that we could take on the 400 Gh/s and 500 Gh/s chips.
If Intellihash is to turn out to be our 'secret ingredient' then it's vital that we stay one step ahead of our competitors and remain in the dark for now.
@drawingthesun, nice post.

Any mining gurus want to speculate with me on what IntelliHash will be? I'm guessing something like variable difficulty - something that increases the nonce search space and cuts down on chatty communication. Or maybe just 48 bit nonces.
If it is a fatter nonce/bigger search space will this up stale rates? Do you build some kind of interrupt so you can restart on the new share right away or do you just let the other hashers finish and give them the new share when they're done? I know jack shit about the tradeoffs here and this EE stuff.
You could try gleaning some information from our illustrious leader via PM. Perhaps you will succeed where all else have failed
The force is strong with this one
I personally think that this intellihash was miscommunicated, but lets assume that it is what Ken says it is; a software that can scale up and increase hashrate of the chips or allow for a competitive chip making process that can give us a constant extra 20%.
If the above is true, and it really is a technology that will give us an edge, Ken will not talk about it and this is the correct business decision. However if the intellihash is a stalling tactic, again Ken will not talk about it.
So if it's real Ken shouldn't be talking about it, because the same process/algorithm/whatever could be used by our competitors, but if it's not real, Ken obviously sill not talk about it.
There is no way Ken is talking about intellihash.
Intellihash(tm)
Intellihash is our new trademark for our new Bitcoin mining software which gives up to a 20% increase in hashing speed
and has the possibility to increase the speed of our mining machines as the difficulty goes up. We have had to modify the software in our chips to make it work with our new software. The chips are going to be late; however, our new Intellihash software could be a game changer for the company.
