Ooh, I'm really excited! Finally another Sonic show!
Sonic's design seems to be the same as always, just with a few more small spikes in the back.
Tails looks EXACTLY the same way as he always does.
I agree the design for Knuckles is a bit over the top, but honestly, it's only his shadow. Let's wait till we see the actual thing. I don't care about him being taller and bulkier...but why the fingers? I'll miss his boxing gloves.
Amy also looks as she normally would, but it seems that she's not wearing a skirt/is wearing pants.
I agree with the poster who said it was stupid to change the design now because if they wanted to do that they should have started with Lost World. Oh well, I'm still excited. I wonder who else we'll see.
