I trust Abrams and I have a lot of faith in this project, but I find Perry to be too self-centered. Sure, it's a cameo and Perry's appearance definitely won't torpedo the film, I just wish he wasn't approached. Even from the blurb we get from the news item, the sheer number of first person pronouns he uses is consistent with how he tries to make his actual name into a brand name.
That's right, I'm expecting to see on the building in huge neon letters: Tyler Perry's Starfleet Academy.
Maybe he was brought in to fill the George Takei "overinflated sense of importance to the project" role.
