Prediction - PS4 will have 20 million lead over Xbox One at the end of 2015

I believe a 10-15m lead is indeed possible. Who knows, maybe even a 20m lead - Sony has the games next year in order to achieve this. For this year though, my prediction is that the current gap of ~5m will widen further to 7-8m at the end of this year.
