Could we be getting game-linked unlockable characters in Smash?

A Neogaf user by the name of Spainkiller has just put out an interesting rumor:
Buying and linking both versions of Super Smash Brothers will net you additional unlockable characters, which may include:
Dixie
Ridley
Chorus Men
Mewtwo

He claims that the rumor is valid because the person who has given him the rumor, is the same one who outed the additional Koopaling skins for Bowser Jr shortly after the ESRB leaks hit the net, and as we all know, that has come to pass as true.

He cautions, though, to continue taking this with a grain of salt.

What's your take on this, N4G?
True or false?

Im gonna quit me job and become a rumor maker on neogaf.

Ridley, one part stage hazard, one part fighter.

[eaise]

Ridley is gonna be a fighter= automatic false rumor :)
Plus this is a stupid thing. I'd be extremely angry if this was actually true.

[Trolltroll]

I would agree but... I still have not seen him as a stage hazard in any of the lvls show on the streams.

[GoPanthers999]

no prob, getting 2 3ds versions for he kids plus the wii u, hope this is true.

To be fair, the guy stated hes seen the character models and is just guessing at how you unlock them. Could be DLC.

They could also be cut content or scrapped ideas. Like Dixie Kong could have been a Diddy Kong alternate like others have, Ridley might have been a stage hazard, Chorus Men probably was considered for a 3DS exclusive stage and mewtwo could have been a poke ball summon or or something along these lines.

I mean, we have one "real" thing to go on here. There are moving models (meaning they could be anything that moves from a summon to playable character), but everything beyond that sounds to be theory and assumptions, which leads me to believe this is false (especially because this doesn't even sound like a Nintendo move).

A little detail I forgot to mention; there was nothing indicating that the characters unlocked would be exclusive to either version; if this rumor is true, it will likely make the fighters available in both versions.

So if true you would need to buy both versions to get all characters....LOL

Wow...just wow

[eaise]

I think this is the only time I have ever agreed with one of your comments. I will not be buying the 3DS version and do not want to miss out on characters because of that. I'd love to have both versions but with limited amount of money in my wallet I have to wait for the Wii U version as it will be the definite version. I hope Nintendo does not make this mistake

[NintySonySoft]

It'll give us 3ds owners and wii u owners a lil gift for having both! :3

[randomass171]

Couldn't resist. Besides this is an unproven rumor. It's silly to act all shocked and surprised when it's as fake as fake could be. It's also silly to not have expected some large incentive to own both versions of the game. If licking "Nintendo's arse" means having common sense about these things then I guess I'll just keep licking. :P

[-Foxtrot]

Want to keep going or do you like being marked down for off topic remarks.

Common sense...lol

If you have to buy both versions to get all characters then sorry but that's a kick to the teeth. Basically forcing you to buy both version to get all content in one game.
