I think that they will announce the release date after Smash Bros. for 3DS comes out.
If they announce the release date now some people will think 'I will wait for the Wii U version, as that will only come out shortly after the 3DS version'.
By announcing the release date after the 3DS Smash Bros. release, it does not draw any attention away from the 3DS release. At this point people will already be hooked and then Smash Bros. for Wii U will have its release date announced for November/December 2014.
I believe it is a strategy in order to balance the sales of both versions of the game.
