I think the 3DS version will come out first, and will hype up the massive Wii U title.

That's precisely why it would have balance patches, to nerf A-tier characters and try to build up E-tier characters. Balance patches would keep the community guessing, especially if they're in ways that aren't immediately apparent.

I think the exact opposite. I think the may been one to 3ds first that comes out this year and serves as intro point into the wii u one that would come out in the next year or so. That 3ds would be fully featured and come with most of the characters and so new ones. It will set the stage for the wii u one. So this may be a very smart idea if everything turns out right.

Hey I never thought of that. I don't need to get a WiiU for Super Smash Bros. I can get a 3DS instead now.

Brilliant!

But people are correct about the local multiplayer on home consoles being better but for myself, my kids are grown and out of the house and my friends are all to busy to all come over simultaneously so 3DS would be fine.

Considering they will most likely be two different games, I don't believeit having both will impact sales very much; if at all.

I don't see it as a issue.....the Xbox and PS4 won't get it. Simple.

It doesn't have to be a exclusive to have a exclusive effect.

I think in this case the Wii U version will come out first.

Smash Bros. U - April/May 2014

Smash Bros. 3DS - November/December 2014

If that's the case then it's no problem, the Wii U will get most of the benefit.

I think the 3DS version may be more of an enhanced port of the GCN/Wii games anyway.

Relax - the Wii U version will be definitive

going to buy both day one, i dont see a problem.

The wii u version will probably be superior, and all the largest fans will buy that version. Also I think in general most others will too, as the multiplayer is the real flesh and bone of the game, and on a handheld multiplayer is a very different beast.
