Actually, from what I know, the polar bear appears as a smash run enemy. Why would he appear if we don't have Ice Climbers?
And they still kept the polar bear picture in the official facebook site of Smash, so they definetly haven´t removed the polar bear.
Well the only thing backing up Ice Climbers right now is their veteran status, because Sneaky Spirits of Rhytmn Heaven also appears as smash run enemies, and we don't have proof that any character of Rhytmn Heaven is playable (yet). The Polar Bear don't instantly make IC confimed unfortunately.
Also, we need a new character confirmation,
fast. We are 3 weeks away from the launch in Japan, the waiting is making us grasping at many little details that is too sad to be funny (Really, we are discussing the details in furniture, think about the irnoy).
Character confirmation (of any kind at this point) can bring a end to this leak. Being characters that are not there, characters with different models, or just some more new information to we change subject a little.
