Yup. There it is. I was going to make it a bold prediction, but it seems very logical to me. Many will disagree, but I say phooey to you!

Combined PS4 and Vita sales will never catched combined Wii U and 3DS sales for the entire generation.

Your thoughts?

PS4 alone will spank em both.

You know, you'll wait like 10 years for that prediction. Till last PS4 console is sold.

What's the point of this comparison?

Nah, by 2018 we'll have a PS5, and by 2020 PS4 sales will be next to nothing.

I don't think I'll be here to prove this right or wrong! PS consoles can have legs of 10 years, I'll be like 35 by then, with kids maybe ^^

Much like the most of the entire internet, it has no point and is just for fun.

No.
PS4+Vita: 190,000,000
Wii U+3DS: 130,000,000

So far this year, Wii U+3DS are under PS4 alone, and PSV is over Wii U. So no, I don't think so.

PS4 - 90 - 110m
Vita - 15m

3DS - 80m
WiiU - 15m

So no, and PS4 could well outsell 3DS and WiiU combined.
