Forum:Big the Cat in Mario and Sonic at the Olympic Winter Games?

I looking at Big's page, and it said he would be playable in the Mario & Sonic at the Olympic Winter Games  Same on the game's page.

I then checked Big's page on Super Mario Wiki, and it said it was hinted he would be playable. I followed the link to a Sonic Stadium article about it, stating:

If you ever wanted to see a purple, morbidly obese cat ride a skeleton luge, this game may make that dream come true.

Knowing that they were being sarcastic, I just want to ask: is he really playable.

If he is, I'm gonna lol.
