Wii U first then the PS4, but I might hold off on the Wii U since the rumors of the PS4's approach are coming closer and closer.

Right now, I don't know if I'm picking up anything. If I do, it will be a couple years from now.

I forgot about the OUYA. I'll probably pick it up too.

PS4 at launch, and wii u down the line, just cant see myself paying for online

All of them like with every gen.

Mainly Wii U, I will always have a PC, so if the third party support for the Wii U is not good then I'll juts buy every 3rd party game for my PC. I will eventually get a PS4 but that will be at the end of it's life cycle. 

all of them I expect, have all the current gen consoles

Wii U I pre-ordered but money is tighter than I expected so may cancel and wait till January before getting it now

I'll get the one which is the most powerful probably if there is a significant difference otherwise probably the PS4 due to the fact that my friends all like Sony consoles better.

nextbox for sure, I highly doubt I'll buy one at launch though. Probably wait a year or two for a price drop of deal.

All three is the only way to go.

1st and 2nd party titles alone is enough justification for that. Otherwise you miss out.
