I plan to own both eventually, but I will likely buy the 3DS version first and the Wii U version as soon as I can afford a Wii U

Wii U. I don't need both.

At first i only wanted the Wii U version, i agree.

Then i found out about A) Smash Run and B) 3DS version is at least a month and a half out front.

Ain't no way i'm waiting that long.

Both versions, because Smash run (3DS) and Wii U for better experience in general. Still hoping for a story mode in the Wii U version!

Both, but the Wii U version is the one I want to play.

I'll get the 3DS version to get the soundtrack from Club Nintendo and to try some Smash Run, but will sell it afterwards.

You bet your ass I'm getting both!
I need both my HD Smash fix AND my portable Smash fix.

Previously, I'd play Smash 64 on an Android phone or something, that game feels pretty lame compared to the later releases.

Maybe this one:

I will only get the WiiU version! Please don't kill me!

Wii u.. The silly gamer in me wants a new 3ds cus of my travelling schedule with train and plane.. But i prefer console software... Bowser jr and shiek will be my mains..

It does http://gamrconnect.vgchartz.com/thread.php?id=181502&page=1 but that was a long time ago, and I think there is at least one other topic with a similar poll posted in between times. 

Still, it's always good to see whether and how opinions have changed in the intervening months.

I'm still getting both, although it might be the Wii U version first and then the 3DS version.
