It not true to hitted the value of $1,000,000 because that is huge value for each one bitcoin and I think people are think also it is not a good IDEA that amount because it is far from the reality . But if the prediction is in real life it is good to see but I don't know why other people predicted to much..
It is a huge value, but did anyone in 2010 or even in 2014 think that the BTC price will reach $20k?! It seems to me that if there was such a person, he did not even want to talking about it loudly. In my opinion, $1M is possible, if it fails in 2020, almost certainly within 5 years.
