I miss the chuckling Knuckles reaction He rolls at random when you walk. Anyway I don't know if he can be a playable character.... either they will make him look clumsy through animations but still give him a normal moveset, or he's canonically too clumsy to do anything. I think that maybe it's another character on the heroes' side that will be revealed later. If playable Trip is a surprise reward, I doubt they would put him in the title screen because it would ruin the surprise; the title screen definitely has a gap, I expect the gap to be filled by the release day (worst case they will just rearrange the characters). If it's a different character completely, I'm not sure if it will be a new one, a known face (Mighty, Ray, one of the Chaotix...) or just Fang, that maybe was left out because the trailer still didn't show his 3D model yet (even though we've seen it in a cutscene). I still lowkey hope that they will screw the canon and put a classicized modern character in there, but I know that it will never happen. There seem to be a little gap even in the final scene of the intro cutscene... maybe the character is there but the layer got disabled so we can't see it? I don't know.
