Looks like the L3 is going to be what the A4 was supposed to be... A game changer. This miner could force the retirement of the Titan's and even the A4's. Of course the devil is in the details.
Are you sure it is not vaporware (hope, hope) gonna put a crimp in my mining my KNC Titans (or folks A4's) into next winter for heat (always my backup plan...squeak into
winter 2017-2018 with borderline LTC asic miners someday and trade LTC for Electric to Heat and call it a draw to wrap up the home mining)
This could get really, really, and I mean really...ugly for difficulty and/or if the price of LTC and/or other scrypt does not surge in price.
To make up the difficulty you likely imho need to be at least at 0.008 ltc to btc from the current 0.00452 ltc to btc now
that would make EVERYONE be able so survive ..knc titans, a4's etc into my winter trick at least (sorry desert dwellers you are on your own)

Anyway we saw a lot of this kinda thing in Feb/Mar 2015 and NONE of the equipment came to pass....a guy can hope it is the same (I am soooo greedy)
but to be truthful knc titans bought in Nov 2014 and added since then to make 3150mh and I can 'slip' into them for even 'heat' this next winter
is way, way longer then I should have expected..just gonna be sooooooo bored w/o miners to play with in the house
