So would anyone like to make any guesses of how many total units both dual-systems ecosystems will sell. For the sake of a date, lets put it at Jan 1st 2019.
I kinda expect a 100M from both pairs - with the PS4 and 3DS remaining each companies trumph-cards, but with the PS4 beating the 3DS by amount as much (or perhaps less) than the Wii-U beats the Vita.
