nope i have a feeling the network will crash because all of the inefficient machines will be forced offline.. it will be like 2009 all over again and small usb miners and cpus will be the only thing mining.
that first week tho is going to be brutal. i bet the block times will go over an hour.
unless they figure out a way to make mining chips use 1/4 the power they do now very cheaply.
it happend with LTC, the block halved and the diff dropped so much i got like 10 blocks in one weekend with my gpu..
maybe it wont be so bad, but i bet there will be a nice drop in difficulty.
