I've had Bayonetta locked into my various prediction rosters as the real "wtf" character (since they came out swinging with Wii Fit Trainer as the "wtf" character.)
It makes sense as cross-promotion (similar to Roy being in Smash Bros Melee before Fire Emblem 6 even released in Japan), and the fact that Sakurai is apparently personally friendly with some staff at Platinum Games. While there are many good arguments against, it's certainly not impossible.

Monster Hunter: pissing me off since 2010.
