May it be the case that ASICminer's stagnation combined with the possibility that most batch 3 avalons are already in the wild cause total network hashrate to be stagnant for the next few weeks? Current (VERY EARLY) projections show a very minimal increase with a very real possibility of a difficulty decrease, will these projections hold?
As some have pointed out, this is an estimated hash rate which fluctuations stochiastically. Chances are the hash rate has increased slightly. Certainly this dip would suggest it's improbable that there's been a rapid increase in hash rate. The only reason why I could see there being a slight drop is if GPUs are being shutdown after the difficulty increases have made GPU power costs exceed revenue.
I can't imagine there being a dip in bitcoin difficulty in ~2 weeks from now short of a catastrophic change in bitcoin price. The rate of increase could be lower than the previous one, which would be welcome news to most miners. But there will be more ASIC miners coming online in the next two weeks.
