I think the price readjustment already occurred over the past 3-4 months when it slowly grow from 380-400 to what's currently today 600-700 range depending on daily movements. If they were mining when 380-400 was enough to cover the fees than I don't think we'll see a sudden spike in price just cause of the halving. My predictions is that by the years end we could yet again touch $1k mark and settle in the $900 for the next year to come.
