I just pre ordered the Wii U version today

Only Wii U.

I haven't 100% decided, but I'm about 99% sure I'll get the Wii U version, and about 80% sure I'll get the 3DS version.

WiiU only. SSB is a local multi-player big TV with friends kinda game.

Definitely Wii U version.
MAYBE 3DS version in a long while or if it has a nice release price.

I'm not going to shell out money for both, and quite frankly, I still maintain just as strongly as the day they announced it would be for both systems, that putting it on 3DS is a waste. The graphics in the 3DS game are, quite frankly, pretty terrible, as in worse looking now than Brawl even, whose character models at least still look good. And regardless of semantics, the Wii U version should have been the only version, they should have focused all their time and effort into ONE game, not two "versions" of one game (with two completely different sets of asset to have to create), and the Wii U version certainly should not be missing out on or lacking any content AT ALL, simply because the 3DS medium and hardware are more limited.

Wii U has a perfectly fine GPU, and BluRay capacity disc size. There is no reason on earth why anything should have to get cut this time. And simply put, the Wii U game being the only version would ensure it's sales. I still believe the Wii U game will sell quite well, but it would been guaranteed strong sales, and thus a bigger system sales boost as well, if it was only a home console game, as the series has always been. And even IF Nintendo was determined to make a portable Smash, they should have done so AFTER this game was finished and released. Done that way, they'd be maximizing the benefit and profits of both games, on both systems.

The way they're doing it now, it's inevitably going to cause some sales cannibalization. And that just isn't smart business.

Sorry, but I'm only getting the WiiU version, because the 3DS version just looks very uninteresting to me.. Maybe I'm missing something.. :-/

Wii U for local multi. I thought about the 3ds one but it just seems kind of pointless when I can have access to the better game.

WiiU only. Local multiplayer is very important in a game like smash bros.

3DS.
