100 million PS4 lifetime is impossible...

I still don't see it. I might be a touch low on my prediction, but no more than 5 million. I just don't see how PS4 can go any higher than 70 million. The PS, PS2, and Wii reached 100+ million mostly because of casual gamers and most casual gamers have moved to phones and tablets. 10-15 million a year for 5 years, then PS5 will launch and sales will drop pretty quickly because by then it will be too insanely expensive to support two consoles at once for Sony.
