Not that I don't want to see the price go to $2000, but it's simply not reachable just because of the block halving. For that to happen there has to be much more demand. I think a realistic price for the halving is $500-$600.
Most of the people are expecting double the price of bitcoin on the event of halving to make sure the mining is still profitable even after halving. I guess, the initial push due to halving will make bitcoin to test previous high too. Let's wait and watch.
