Sonic: Looks pretty kick ass but im getting used to the new blue arms and longer legs, still very cool though i dig the scarf
Tails: Overall he looks the same but with a utility belt and goggles, and they fit him VERY nicely
Amy: So far my favorite of the redesigns, they really improved her alot(not just talking about clothes but in intelligence and fighting skills too, now shes the most acrobatic of the team) so thumbs up!
Knuckles: I get the whole "updating his image to make him look as strong as he is" and all but it'll take me a while to get used to the new look, it's neutral for me
overall i hope the new game is awesome and i hope the series is successful like Transformers Prime(at first glance looks meh but ends up being very cool to watch)
