Zelda Informer's review says so:

Not sure I like this information much, I thought the final boss would have been a great part of this mode, and to hear it doesn't even have the final boss (and likely not a special/secret boss either) is a bit disappointing in comparison to Brawl's Boss Battles mode or the Gauntlet from Mario and Luigi Bowser's Inside Story.
The rest of the game is likely great though, just a minor exclusion of content here.

There is no Ganondorf in the boss mode
