PS3 - 107.5m
Wii - 102.5m
360 - 100m
3DS - 100m
PSP - 85m
Wii U - 55m
PSV - 40m
PS3 will sell a lot during the next few years after few price cuts and with decent 3rd party support. PS4 not having BC will keep the PS3 sales strong.
With M$ supposedly making a slimmer 360 model which will be cheaper and knowing that they're aiming for the 100m mark, I don't think they will give up on it until it reaches that figure. With the cheaper new model, future price cuts, still receiving decent 3rd support for the next few years and the Xbox One not having BC this will mean the 360 will sell a lot over the next few years.
The Wii's not selling much nowadays and with no support in addition to the Wii U being BC I think about 3m more sales lifetime seems fair.
The PSP seems to be doing quite well for itself in Europe and Japan at the moment, could sell almost another 6m.
The Wii U should pick up when more worthwhile games arrive and even more so after an official price drop. Since the Wii U's gamepad gimmick is not catching on like the Wiimote thus losing a lot of casual gamers interest and with most core gamers who are not interested in Nintendo's IPs looking forward to PS4 & Xbox One... I think It'll settle between the NES & SNES.
I'm expecting the Vita to sell a little less than half what the PSP will achieve.
There's my predictions, probably rubbish but hey, I'm no analyst.
