An unusual teaser site has been opened by Game Freak which displays a silhouette image and the words “coming soon”. A caption was also posted underneath the image saying, “the well known game, played all around the world, is about to be reborn thanks to a surprising collaboration”. Knowing that Game Freak is most famously associated with developing the Pokémon games, there’s mumblings that this teaser site could be related somehow. Plus, there’s confirmation that it’s a well-known title, which presumably leads us back to Pokémon.
Although Game Freak has worked mainly on the Pokémon games, they have branched out and developed Harmoknight in 2012, Drill Dozer in 2005 and, before the release of the first two Pokémon games in 1996, they developed a Yoshi title in 1991, as well as a Mario and Wario title in 1993. But there’s no denying that the silhouette looks more like a Pokémon than any other games in their roster.

The official GameFreak website has posted a strange picture of a silhouette with a caption noting that "the well known game, played all around the world, is about to be reborn thanks to a surprising collaboration". Now, this may not be regarding Pokémon, but rather another franchise that GameFreak is now working with, so don't take this as Pokémon at this time, but we'll bring news as and when it comes
I have a feeling this could be that so-called "Scoop of the Century" coming in next mouth's Corocoro issue.
