When the hard fork happens the amount of dollars($'s) in BTC itself will cut in half. The remaining value initially I believe would be split 4:1 in favor of BTC.. Over a 12 month period I see the market gaining confidence in BTU, with it slowly surpassing BTC in support before eventually exterminating the old BTC and taking its reigns. Over this period price will skyrocket to $5k before the next leg of adoption to $50k as a result of successful scaling.
