There's plenty of time for Nintendo to fill out the first half of 2015. Personally I'd expect one or two more Directs in the next few months. One a general Direct like this, for release dates and software announcements, and another for New 3DS launch plans.
First half is any time up to June. For now, the only thing we know is that there's Smash this month, Captain Toad is December/January, Mario Kart DLC is May and Splatoon is down as quarter 1. Yoshi and Mario Maker might yet make it into the January to June window. It's not as if there's much else there.
