Having a huge potential with ETH in the future is quite possible and I believe we are going to definitely see this happen for sure. However, we can't really put price tags like these in our brain and hope for the best, just say it will go up and you will be happier. Plus, this isn't something special to ETH, we are going to see other coins go up too, bitcoin will probably be 500k or maybe more by that time as well. This isn't some dig at ETH, we are going to see ETH be great, its just so simple to see that we are going to get great results from other coins as well so its not JUST about ETH and what it will do.
