The rumored mash-up between Super Mario and Raving Rabbids has recently been confirmed. More recently, however, we've seen leaks on Amiibo to release alongside the game, now titled Mario + Rabbids: Kingdom Battle.
According to a summary article from Nintendo Everything, Amiibo support seems to be planned, and prototypes of the game feature a mode called "Amiibo machine". As pictured, Ubisoft seems to be producing prototype figures of some of the game characters.
The game has actually been revealed to be in production for three years and we're just now hearing leaks about it.
We've seen more details of the game here, and we expect more to be revealed at E3 next week.
