WiiU, the Nintendo exclusives are still better than the AAA multiplats this days.

WiiU. Everything the WiiU doesn't have, it's on my computer. Also Splatoon and Pokken Fighters (eventually). Also I refuse to pay for my multiplayer.

Wii U. I just enjoy their games the most : )

XB1, as I don't have the PS4 yet to give me reason to say it. The longer time that passes, the less likely I will get the PS4. I am not missing it yet and when I have played it, it has proven to be basically the same thing for console games as the XB1. But, the XB1 has a number of minor features that I like that I won't want to give up now that I am used to them.

I would have to go with the PS4. Because while I really enjoy the Wii U, and missing out on Zelda would Hurt quite a bit, the reality still remains that there aren't enough games that interest me releasing for it outside of the Nintendo titles. The droughts are quite long and that just won't do for me.

The PS4 gets all the third party games I like, like The Witcher and Final Fantasy, while receiving quite a good amount of compelling first and second party titles.

Wii U :
I couldn't pass up a Zelda,
Splatoon I think I am going to really enjoy
They have to have something for 2016 and I'm hoping that is another Metroid

My PC.  I meant those games will be avalible on PC. I mean, most publishers nowadays just put their console games on PC months later, cheaper and with less bugs. The only ones that don't come are the exclusives, but what can I do about that?

Wii U. More games I like and free online.

PS4.
Will most likely have the most successful AAA new IP's (again) to keep things fresh, on top of the great IP's they will continue (like uncharted), and the best versions of the biggest multiplatform games. Not a huge fan of indies but when PS4 has tons releasing all the time, im bound to pick up and enjoy a handful of them.

Also prefer a symmetrical controller... and good shoulder buttons which I can assign ADS and shoot to whenever available.

In that case I would still choose WiiU. After all, my main platform are handhelds, and OP doesn't say anything about it XD
