With a 59% or more rise in difficulty next increase (https://blockchain.info/charts/hash-rate) I wonder whether I should cancel my Saturn order?

All manufacturers seem to have large orders due to be shipped before KnCMiner ships so Jumps of 110,000GH/s per fortnight may continue several more times if not each difficulty change.

Current jump is more than total capacity beginning of June!

I had been thinking of upgrading Saturn to Jupiter. Now it's unlikely. More likely I cancel during next few weeks while I still can!

Hopefully their planned March 2014 offering will make a good investment & ROI.
