The URL of that pic has the word "ike". Is Ike in Mario Kart Wii!?!?!?
If that's wrong, Max is still technically correct if you spoiled the fact that there are new-to-the-series racers in MKW.
Any answer or response to this post will probably be considered further spoilering.
P.S. How about Diddy Kong Racing? Can that be spoiled?
