Beyond working on a secret blockbuster project, mastermind Hironobu Sakaguchi is also plotting a new title, we hear.

The Mistwalker exec has been teasing about his plans in recent weeks, the boss refusing to be drawn on the identity of his new triple-A offering, while also promising an iPhone game.

In a 'happy new year' message on the developer's website, Sakaguchi says an iPhone project "should be released soon", but we aren't offered any word on what the new title will be.

Mistwalker have created Blue Dragon and Lost Odyssey in the past, but it isn't clear if either of these series are linked to the new mobile project.
