Not explicitly shown in the trailer, but visible in artwork and this background shot, is Talonflame. The X&Y ember eagle will arrive with its evolutionary forebears.
Benjamin was born in 1987, and is still not dead. He variously enjoys classical music, old-school adventure games (they're not dead), and walks on the beach (albeit short - asthma, you know).
He's currently trying to compile a comprehensive history of video game music, yet denies accusations that he purposefully targets niche audiences. He's often wrong about these things.
