Pikmin 3 makes me want it, a lot. However I'd prefer to have more than one title to hype over, plus some actual features and information. they only announced three first-party titles, and only one of them was any good (though some people enjoy the New Super Mario Bros. series). :c
i really liked the tablet controller after seeing a few things about it today and/or sunday, which reminds me I want to see the Pro Controller in action too
