Last Gen Sold 280m Consoles. How much will this gen sell? Predictions

[itsFizz]

I think we will see an in between of gen 5 and 6. The 5th gen(ps/saturn/n64) sold 146m while we saw growth in the 6th gen to a cummulative 213m (Ps2/DC/GC/Xbox). My guess would be an overall sell through of ~180m
Ps4: 100m
XBone: 62m
WiiU: 18m
