3DS is set up for a truly stellar year with Fire emblem and Luigi's Mansion already out, and Donkey Kong Country Returns, Link to the Past 2, Pokemon X/Y, and Mario and Luigi: Dream Team coming out throughout the rest of the year.
Honest question, what does Vita have to match that? I know about Killzone, Tearaway, and Soul Sacrifice, and I suppose you could add Sly Cooper if we added Donkey Kong to the 3DS's lineup, but that's it. Not nearly enough to combo the 1-2-3 punch of Zelda, Donkey Kong, and Pokemon.
