500 million. Home consoles will grow but handhelds will shrink. We did a bit shy of 300 million home consoles last time so that would be about 250 million PS4s, 50 million Wii Us, 50 million XBONEs, and 50 million Vita.TVs.
Handheld did about 230 million last time so thats 80 million 3DSs and 20 million Vitas.
Most of those numbers look a little ridiculous after jotting them down.
