Was sebbbi one of the team members in the audience that appeared on camera at the end? I don't know what he looks like. Although, this is probably a side project he is not too involved in while he works on next-gen trials.
My personal opinion about the footage: The levels look too much rollercoaster style. I personally like slow paced skill demaning hard/extreme Trials levels more. Cutscenes just aren't for me. I prefer pure speed running with instant retry, full leaderboard integration, ghost opponents, etc.
