Just like that, the rumor has been squashed. Our good friend Ishaan Sahdev over at Siliconera spoke to Reuben Langdon via email. Turns our Mr. Langdon was actually getting Playstation All-Stars Battle Royale confused with Smash Bros.. This direct quote comes to us via Sahdev.

"Oh, the all-stars battle Royale was the one I was in. Lol! Yep. Totally got them confused." - Reuben Langdon

That's quite a big mistake to make, but at least we have it all cleared up now!
