Hasbro has some last minute release of the official images of Sentinel Prime that will be released in the upcoming Titans Return line.

Just like the rest of the figures in the line, Sentinel is also a Headmaster with Autobot Infinitus as his head. And like the Voyager and Leader class figures, Sentinel is a triple changer: transforms from robot to Cybertronian shuttle to a train. I definitely smell that this figure will be retooled to Astrotrain. Sentinel Prime will be released as a Voyager class figure.

Thanks to TFW2005 for the official images.
