Wii U: never I guess
Xbox One: also never unless MS surprises me with a game I absolutely must own
PS4: possibly when the next Uncharted releases, depends on its reception and my financial situation. If Uncharted's bad or if FF releases earlier then replace it with the FFXV launch, been wanting that game since it was announced, but what are the chances of a ND game being bad or FFXV releasing before it.
Vita: Never, not interested in handheld gaming
3DS: same as Vita probably, but if I were to get a handheld it would be the 3DS

I'm not sure which console i'm going to buy yet, i'll let the next year determine that for me. So....

PS4/XB1 - Fall 2014

WiiU - When Smash Bros is released.

WiiU - Own
3DS - owned maybe again at some point
Vita - Never
XBoxone - Never
PS4 - Never

PS4: 2014 when infamous released, i realized that i don't need it right now. my cousing bought one and he live near me so i will play on it from time to time.

xbox one: probably never

Wii U: waiting for mario kart 8

Wii u: Probabily I will buy next year, but I hope to have money to buy on december, I want this console since I knew it was a new system (early 2013)

3ds: When I have money after buying a wii u, I only want pokemon

Ps4: When gets really cheaper and have a good games library, the only game that i'm interested for is infamous

X1: Same as ps4, I'm only interested in Ryse and zootycon (if i get a ps4 first i will not buy a x1, the opposite will work too)

Vita: Never, not interested at all

PS4- unless i can import it, when it is available in y country as sub 500$.

PS4- Late 2014. More games- Destiny/Infamous/MGS 5/Uncharted 4, possible price drop or new SKU/bigger HDD.
X1- A couple of years after the PS4, if I get one. 3DS/Vita/PS3/PS4 will take up so much time.
Wii U- probably never for the above reason.

PS4- When the new Uncharted/ND game is out.

And probably not going to bother getting any other console this gen.

Sticking with PC, PS3 and 360 till then.

I'm not into that open swapping lifestyle!!

Already got a Wii U.

PS4 when Kingdom Hearts 3 will come out. :)
