Yes. Three. We have three taunts instead of one. It gives more variety and it's a great thing! Just check it out for
yourself! It shows taunts of various characters.
I can see Sonic harking back to the old days, him using his "no" finger, waggling it at others just like in the opening for the Genesis game, Sonic the Hedgehog and StH 2 (correct me if I'm wrong, but I'm ashamed if it's wrong). It just adds to the official taunt that was annouced for one of the three, which is Sonic spinning his shoes around and saying "You're too slow!" Right on character.
Sooooo, any speculations on what some other taunts can be for any of the announced characters?
