Nintendo has long resisted the call of mobile gaming, but today it entered the space in a big way. The company has announced that it will team up with DeNA, a major Japanese mobile gaming company, to make smartphone games featuring Nintendo characters. The two companies "intend to jointly operate new gaming applications featuring Nintendo IP, which they will develop specifically for smart devices," Nintendo said in a statement.

Nintendo has flirted with mobile gaming before. In a tie-up with GungHo, the company will release a Mario-themed version of Japanese mobile smash hit Puzzle & Dragons for 3DS next month, and recent experiments like Pokémon Shuffle have adopted similar free-to-play business models.

We're at a hastily convened press conference in Tokyo that's due to start soon, and will bring you any further news as it happens.
