It was just confusion.

EDIT2: He explicitly says played and not voiced, so it could be just confusion.

Now the first thing that comes to mind is PSABR, but...
http://www.gonintendo.com/s/225510-raiden-not-appearing-in-smash-bros-wii-u-3dsJust 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! Also worth noting, Langdon was actually talking about mo-cap work and not voice work.

It's possibly worth mentioning that Reuben Langdon is primarily a stuntman and motion capture actor, so that may be what me means when he says he "played" Raiden. I don't think Smash Bros. uses any motion capture, though... maybe in one of those CG trailers they've been making?

From the Smas Bros 4 Discussion Thread:
The part of the article in question:Why is Reuben Langdon saying he voiced Raiden in Super Smash Bros (right at the bottom of the page near the Raiden pic)? I can't remember Raiden being in Brawl?
Is there a game franchise you'd particularly like to appear in?
Let me think about that. Well the Metal Gear series is always coming in and out of my ‘field’. We have put bids out on it a couple of times. Raiden was always a character that I had wanted to play. I did end up playing him on Super Smash Bros; so I did end up playing him eventually. NOT to the extent that he is in the other games.
Now the first thing that comes to mind is PSABR, but...
"Raiden was always a character that I had wanted to play. I did end up playing him on Super Smash Bros; so I did end up playing him eventually."
I would assume he meant PS All-Stars.
Edit: Or maybe not. I only see him as the voice actor for Ken in SF4 & Dante from DMC. Nobody has him listed for PS All-Stars. Perhaps he's a new assist trophy, should Snake return....or maybe appears in codec conversations, which would be awesome if those happened to return along with Snake.
And what about Gray Fox in Brawl?Yeah Quinton Flynn plays him in PASBR, so I don't get what the heck Reuben is talking about. I hope this means Snake is in Smash 4.
So yea, is this an actual Smash Bros leak? And he probably will be an Assist Trophy if he is in, so don't take this as a confirmation of him being playable.Did a voice actor just leak something big here?
Who voiced gray fox in brawl?
Edit: Rob Paulsen did, and Raiden did not appear at all in Brawl I'd call this an honest to good leak
