In CoroCoro magazine in Japan, Game Freak announced a new Pokemon in the upcoming Pokemon X and Y and that Pokemon Rumble will be making its way over to the Wii U eShop in Japan.
The new Pokemon revealed is Ninfia, which is another evolution of the popular Eevee. According to the reports, there is a secret to getting this evolution to occur. This means Eevee now has eight variations of Pokemon that it can transform into.
The Wii U entry of Pokemon Rumble will include all 649 Pokemon with the ability for 100 monsters to battle against each other at one time. This is a huge increase from the ability for only four to face off at once on the Wii version.
No announcement for a western release has been made at the moment but given the popularity of the franchise this seems like it will make its way to the west. Trainers get ready because 2013 is going to be jam packed with Pokemon and those Eevee breeders are going to be busy.
