Jrpg fan... Sony's forecast is  60m ps4 shipped  as of  March 31th 2017, 3ds alone will be very close 60m as of June 28th 2016... Do you want to revise this  prediction?

So PS4 would have to sell about 15-20m from 1st April - 31st December 2017? His prediction doesn't seem that unlikely to me...

               Hmmmm 3ds should be at 66-67m and wii u at 13.8m-14m  ( always going by Nintendo's forecasting, they may miss it, in that case the 15m would be the needed ) as of december 2017... So, 20m-21m in three quarters, in the 4th year!
