Update: It seems that Nintendo has reversed their previous decision, now allowing the Evo 2013 tournament to return back to its original schedule with Super Smash Bros. Melee streaming. It is unclear what exactly made Nintendo change their mind, but it's good to hear the game is now back in the tournament. The following quote recently appeared on Shoryuken website:

I’ve just receive word from Nintendo that the Evo Smash Bros. Melee stream will be allowed to proceed. We will be restoring the original stream and tournament schedules. Obviously this is a huge relief for all of us here and we’re thrilled that the world will get to see the best Smash players fight it out this weekend. Thanks to everyone online who supported both Evo and Smash, and thanks to Nintendo for allowing us to stream their game.

Original Story:

With just under three days to go before the world's biggest fighting game tournament was to go live, publisher and developer Nintendo has told Evo 2013 organisers that they would not be allowed to stream the Super Smash Bros. Melee GameCube title (via Kotaku).

Taking to their news site Shoruyken, the organisers of the event revealed that a schedule change had occurred due the team being told by Nintendo of America Inc. that they "do not have permission to broadcast Super Smash Bros. Melee for Evo 2013." The sudden action has caused the event to replace the finals with "a mix of Persona 4 Arena and King of Fighters XIII."

It is unclear whether this recent streaming ban has anything to do with the previous crackdown of Let's Play videos showing Nintendo content, which caused a number of angry users to brandish their pitchforks when told they couldn't monetise their videos. It seems that this is the first stream ban that the Evo event has received, with a number of other titles including Warner Bros.’ Mortal Kombat and Injustice as well as Capcom’s Super Street Fighter and Ultimate Marvel Vs. Capcom 3 able to stream freely.

CEO organiser Alex Jebailey revealed to Kotaku that "as a supporter of Smash, this is very disappointing [for them] to take away a great opportunity to showcase Smash."

“I personally hope they can review the situation and understand how important this is for their fans to support them,” Triforce Johnson told us. “I am one of those fans.” The man is at the perfect nexus for caring about this one. He’s a dedicated Nintendo fan — note his first name! — wears a Power Glove in public and manages more than a dozen gamers who are competing in various games at Evo. Johnson implored Nintendo: “Please allow EVO to stream Super Smash Bros. Melee.“
