I would. And I resent the implication that I'm so blind as to fall into a "trap" of some kind.
I don't have internet access where I live, so that's a non-issue for me.
As far as I can see, 3DS has more that appeals to me compared to the WiiU. More interesting stages, portability and City Trial: Smash Edition completely smack WiiU off of the stage. Which only has prettier graphics (Another non-issue for me, my TV is pretty damn small.) and more music.
So unless something genuinely different shows up for the WiiU version, it's very likely I'd rather have the 3DS version.
