Woah, where are you getting 190m from? Vita will do 15m (20m max). so 170m for PS4? At the rate it's selling it will need to be the lead platform for 15 years to get there.

3DS - 75m
WiiU - 15m

I think PS4 and Vita can reach 90m combined, PS4 should be able to do it on its own if this generation goes on long enough.

WiiU and Vita are as worthless as each other. They'll both be a drag on their more desirable counterparts. That being said: Who cares! PS4 will rule the roost and beat WiiU. Vita is so dead that it's not even a thought.

Tie? What a party pooper!

↓↓↓ (my opinion of course)

The generation is young, so it's hard to tell, but I do think Nintendo will ship more hardware overall.

Thing is, Sony is in a bit of a catch-22 in this comparison. I'm guessing that if/ when the X1 overtakes the Wii U, Nintendo will pull the plug on it. They will no longer be able to compete in the console space. If the Wii U flops hard enough to do that and gets EOL'ed around, say, 2016, then the 3DS will get so much first party, third party, and indy support that the PS4 will have it's work cut out to overtake it. Conversely, if the Wii U holds on, you have two Nintendo consoles, the handheld market-leading 3DS and likely the middle of the console market Wii U. That's a better combination than first in market/ last in market.

When you look at Sony, though, there's no chance they will EOL the Vita, even if it stays forever a nobody. I could be terribly wrong, but I see the Vita factoring into this much less than the Wii U.

Cant see wii U doing much better than the vita, but I can see the PS4 killing 3DS on sales, so im gonna have to disagree and say PS4 + Vita > Wii U + 3DS

How would the Wii U ending its life in 2016 influence the 3DS's third party and indie support?

Yupp... hell I wouldnet be surprised if the 3DS actually tops out between 70-75 million LT. Even if the WiiU reaches 25 million, I still think that it will be an easy win for SOny this gen.
