Thief 4 (or 'Thi4f') looks set for a GDC reveal late next month, after Square Enix announced a talk on the game's audio by staffer Paul Weir.
The session, titled 'Stealing Sound: Generative Music in THIEF', will mark "the first time that the game has been spoken about," reads its GDC blurb.
"Developers should more enthusiastically embrace alternative music models to resolve ongoing issues with linearity and to create a musical aesthetic that pushes away from the shadow of film," it reads.
The session description goes on to commit that the talk will mark "the first public insight into Thief and its generative music engine."
Just like a real burglar, Thi4f broke cover back in May 2009, then it slipped back into the darkness, taking all of your expensive power tools with it.
Eidos Montreal boss, Stephane D'Astous promised in the same year that the fourth game in the series was shaping up nicely.
"Let me reassure you that the team is making leaps and bounds. Personally I have NEVER seen a team, at this milestone (middle of pre-production) in such good shape," he said.
