The game is rumoured to be based on Melee and S4

tfw Mew2King became a Nintendo Ambassador not too long ago, but still doesn’t get invited.

I'm surprised Mew2King didn't get invited. Out of all the Gods of Melee he's my favorite.

I'm really happy they invited Melee and Smash 4 players though, it gives me hope.

I think you're asking too much of him

M2K not getting invited is odd as he's the most adaptable of all the high level players it's likely he couldn't make it, Mango is a smart choice though.

The rumor has been debunked by certain sources. I don't know why people still keep it as trust worthy.

Just to clarify, this rumor? https://t.co/Qk3EXZiUA9

100% confirmed fake. Your welcome.....not that you need me to tell you, he got most information about the online wrong.

Not really debunked as he got things right even the day information would be released someone in the replies to the tweet even hits on this it's not debunked yet.

The best part is that we're probably going to get other conflicting rumors about Ninty E3, which might deny his statements if one of them becomes true.

Although, we're gonna be set on the first minute of the Spotlight ....

Man, Spyro and Crash would be such a joke for SSB xD
