This History Of Pokémon Video Ends With A Mysterious Tease

At the Pokémon Game Show, The Pokémon Company ran a CG video depicting the Pokémon series, with a look at the different games, trading cards and other products over the years. As reported last night, the reel ends with a high-quality CG scene depicting a Blaziken and Lucario about to face off, and you can watch the clip in its entirety below, courtesy YouTube user Sizuma1:

While the entire video is CG, the little face-off scene at the ends seems a little too deliberately placed to not be interpreted as some sort of tease. The question is, what are they teasing?
