Siliconera dug up these four vids from YouTube for your viewing pleasure. The first contains the aforementioned lightning and a glowing child. The rest are long, drawn-out conversation scenes between the game's many characters — including class clown Mark (and somehow his hat looks dumber than it used to).
There's no mention of a US release for the Revelations: Persona port/remake (called Megami Ibunroku) yet. But cross your fingers the Persona fanbase has grown enough in the last 13 years or so to warrant one.
