PS4.
I couldn't miss out all that Nep Nep. Also, third party exclusives.

Wii U. I wouldn't be able to see Zelda go by and not play it. That's blasphemy.

My Xbox One is always on.

Wii U... since this is the only Gen 8 console I have right now anyways..

Halo 5.

PS4 - my gaming diet has always been 3rd party heavy, so if there's no PC in the picture, PS4 would be logical choice.

Touch choice. I like all of them for different reasons, but I would have to say PS4. Sony has proven the last multiple gens that it has the best exclusives. Not since N64 era Nintendo has anyone had better exclusives, IMO.  PSN sales and PS+ IGC destroys its competittion completely as well.

PS4:
- Expected great first party titles to come (Uncharted, The last of us, Gran turismo, Gravity Rush etc...)
- Unexpected great first party titles to come
- Great 3rd party support for exclusives and multiplatform games (Persona 5, Yakuza, MGSV, FFXV etc...)
- PS Plus offering of great deals, free games, online mp
- Flash Sales!!!!
- Trophies
- Blu-ray/DVD/Netflix/Crackle/Youtube

Wii U. Zelda.

The PS4. The WiiU's lack of 3rd party support would make it pretty unappealing (i couldn't go an entire generation without all the great games 3rd parties make), and the X1 is missing a lot of the more niche Japanese series i enjoy (Persona, Disgaea, etc). I'm also a big fan of FF14, which would be another selling point for the PS4.

In reality i plan on owning everything at some point though, with PC being my primary platform of choice.
