You'll be lucky to see PS4 + XB1 + Wii U hit 155 million by end of 2019.

By the end of 2019, the PS4 *could* potentially be over 100m imo.

The Xbox One & Wii U should be able to cover that 55m part.

I think by end of 2019, the PS4,XB1,WiiU will in total be over 155m.

It would need three straight 20 million+ selling years to accomplish this, it did around 17.7 million last year with some pretty poor competition. Is this really realistic thinking? What will maintain this momentum over several years?
