Nintendo is soon expected to announce their first mobile game as part of their partnership with Japanese mobile developer DeNA.
DeNA recently released its financial report for the first quarter of the financial year starting last April, and mentions the partnership, stating that they are "currently making announcement plans".
Meanwhile, Nintendo-related property Pokémon has made a number of mobile appearances in Japan, with strategy guides, rhythm games, and even a port of eShop hit Pokémon Shuffle available in App Stores. An official Pokédex app is also available in the West.
The game is expected to be released this Autumn. Further details are currently scarce, but stay tuned to Cubed3 for the latest information on Nintendo's latest venture.
