"Over the next few months we are bringing online enough hashing power to make sure that any delay in the Neptune timeline will be compensated with a completely free hosted hashing packages to all fully paid customers."
Can't people read the word DELAYS??
This means if they deliver in Q3/Q4/2015, you will get compensated with hashing power from their datacentre and they won't charge you for the hosting/electricity.
It seems they know for certain Neptune will be late (
Q2), if they are promising this now.
I would say this would be true for the last batch of neptunes that were listed as delivery in Q2.
Due to the batches, one would generally expect B1 customers hashing power would go online before this.
