I'm not looking forward to it. It is comedy focused and I don't think Sonic should be like that plus Knuckles' design is creepy. If you are going to make the characters realistically proportioned then go all out and make them as tall as Humans to. Don't make them a creepy hybrid between the two.
I wouldn't mind an original character becoming a main cast member as long as they are lovable and have a sympathetic story and don't get more focus than Sonic does. Basically another Chris Thorndyke character is what I'd want.
