Super Smash Bros. 3DS over Wii U: Did Nintendo Screw Themselves Over?

Will Nintendo’s insane gamble work? I ask because there are a few factors to consider when the possibility of failure is involved. What’s wrong with releasing the 3DS version when the Wii U needs it now more than ever? For one, everyone who buys the 3DS version and enjoys it will have acclimated themselves to the core game for 5-6 months prior to the Wii U release and will have no need to buy the Wii U version since overall, it’s the same damn game. Nobody likes buying the same game all over again, or so they say.
