WiiU: 9.8m
PS4: 15m
XB1: 11.5m
3DS: 55m
PSV: 9.8m

no real research done just quick guesses.

I edited my 1st post Seece, with predictions

Awesome, thanks.

3DS = 62.5 million

ONE = 7.5 million

PS Vita = 9.5 million

Wii U = 15.5 million

PS4 = 12 million

I predict that the PS Vita has hit its peak in 2013. Expect the sells to go down YoY for Vita.

Everything else I believe will be up YoY.

Wii U: 10.8m
3DS: 54.5m
PS4: 15.3m
PSV: 10.1m
XB1: 12.2m

Too many variables to jump into conclusions at this point. We don't really know what's going to be the X1 and PS4's real baseline once the dust settle. We especially don't know how is gonna be PS4's reception in Japan.

And about the Wii U, well, I guess we need to wait and see what is goingt to be Iwata's plan to turn things around. I truly believe there will be another price cut and maybe a SM3DW or MK8 bundles.

Anyway, let me throw in some numbers just for the heck of it:

PS4: 15-16 millions.

X1:  10-11 millions.

Wii U (without price cut) 9-10 millions.

Wii U (with price cut) 11-12 millions.

3DS:  55-56 millions.

PSVita:  10-11 millions.
