[Lumastar]

Rhythm Heaven stage.

 

[Nysic]

The Duck Hunt trailer

 

[Tyrell Badd]

Rainbow Cruise rears its ugly head

 

[Lumastar]

The Duck Hunt trailer

Somebody already suggested that, but nobody has suggested a Duck Hunt stage yet. I'm betting that it will be shown in the trailer.

I hope that stage leak is at least true, that would be amazing.

Are you talking about the one that basically been deconfirmed five times now or am is there a new one I don't know about?

Also, guesses for me:

Kalos Pokemon Stage "officially" revealed, along with a new Zelda stage and many others.

Assist Trophies such as Issac returning, but new ones such as Chunky Kong (I heard rumors...) being shown off as well.

(I know it says 1 per post, but I rather not double/triple post and I know you want those 19 slots to be filled)

 

[Magikrazy]

The weird outfits from that one commercial as palette swaps

 

[Xiahou Dun]

If it is what I'm thinking, when how about no? Except for that one disaster, maybe.

 

[Baby Mario Bloops]

Not sure if this counts, but a lot less Kid Icarus stuff (meaning that it's not as over-rep'd in the Wii U version).

 

[Magikrazy]

It's what you're thinking

 

[Mario4Ever]

Ridley becomes the only playable character.

 

[Cirdec]

Ridley shown as a stage boss.

 

[Smashley]

ridley will not be revealed in any way, and his role in the game will remain a mystery

 

[Magikrazy]

Ridley will not appear in any way, shape, or form
