I believe it will, likely between the 21st-23rd which is a month out from release as game specific directs tend to be. The game is worthy enough for one, could certainly use one to further help regain trust after Ultra Smash. That we still don't got a date for the pre-launch tournament makes me think it's a sure thing now. They haven't announced the time yet because they're waiting for the direct to do so. Plus since the March direct we've heard nothing about the game despite it's imminent release.
And yes, I'm also hoping for this so it doesn't have to show up in the E3 presentation. :L
