Did you know there have been 16 Pokémon movies to date? I didn't, but apparently there have, because the 17th one is coming out in Japan this July.
Serebii.net reports that ahead of the new movie's release, a new Pokémon game is on the way for 3DS, and interestingly, it's a free title based heavily on the system's StreetPass functionality.
The Band of Thieves & 1000 Pokémon, as the new game is called, sees you collecting sticker-style depictions of well-known Pokémon and then taking them into battle against thieves based on characters from the new movie, with the results being determined by the number of Pokémon you've successfully collected. Hopefully there's a little more to it than that, otherwise it's just a Pokémon-themed version of existing StreetPass title Find Mii (aka StreetPass Quest). That said, the new game is set to be a free download -- and only available for a limited time -- so perhaps we shouldn't get our hopes up too much.
The game is clearly intended to be a promotional vehicle for the new Pokémon movie -- similar to how many modern films have companion mobile apps and games -- and as such a Western release will likely be dependent on two things: the movie coming out in theaters in the West, and there being sufficient demand for the game. Nintendo's Western arms have so far claimed they have "nothing to announce" on the subject.
