Coming from the EVO site...
Regrettably, we’ve just been informed by Nintendo of America Inc. that we do not have permission to broadcast Super Smash Bros. Melee for Evo 2013. In light of this, we must make the following changes to the schedule.
Smash has been removed from the stream schedule and replaced with a mix of Persona 4 Arena and King of Fighters XIII
Smash Finals have been moved from Sunday to Saturday, 2:00 PM
