I've seen several people state that because of this news they will be getting both versions, and I echo that sentiment. Before, I prioritized the Wii U version, as there was no way I would spend that much money for a lesser version of the game when the superior one was readily available. And now the 3ds version also serves as an advertisement for the Wii U version, which will get a holiday release to boot. It's a much better idea than having them both release at the same time, which would only hurt sales for both.
