Why wouldn't the game-specific Directs count?
We had two Directs this year, there's no such thing as a 'proper' Direct. We've had plenty of months in the past that only had a special Direct instead of a 'regular' one as well as months that didn't have a Direct at all. You can expect a dedicated Mario Kart Direct next month, so that would be three Directs in five months, which is more than once every two months and is the average for these things to come out. Four even if you count the Tomodachi mini-Direct.
They're probably saving a few new things for E3 now.
EDIT: So far though they've been following the scedule of 2012; big Direct in Februari, smaller one in April. Could just be coincidence, but hopefully that means they'll also follow 2012's E3 scedule; a small Direct as a prequel to the conference, the conference and a small Direcct afterwards detailing some stuff further.
