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.

PS4 > 3DS + Wii U + Vita

Maybe, PS4 sell even more of 3DS+Wii U+XOne...

PS4 alone will oursell everything else.

PS4 will outsell the 3DS + Wii U without Vitas help IMO.

Well if my predictions are correct PS4+PSVita will sell 10m more than WiiU+3DS.

PS4: 90m
PSV: 20m

3DS: 75m
WiiU:25m

PS4: 95m
PSV: 15m

3DS: 75m
WiiU: 25m

Why 96? It seems like such a random number when all your others were divisible by five.

It says 95.......

I think theyll be pretty damn close.

Wii u:200
3ds:245

Ps4:30
Vita:6

Look I can make up numbers 2

My bad. I also owe one Mr Adolf Hiller an apology.
