Tecmo has invited US press to the unveiling of a new title in San Francisco in the week of the Game Developers Conference.
The launch takes place at the city's PlayStation Store on Tuesday 24th March - leading to the assumption that it's a PSP or, more likely, PS3 title.
The invitation bills the mystery product as "the greatest _____ game ever".
Sweet, innocentGamespot assumes the space to be a missing series title such as Ninja Gaiden or Dead or Alive. Let's just say that that's not the first thought that popped into our heads. Kotaku is more on our (low) wavelength.
That said, a new Dead or Alive isn't out of the question, as Tecmo has previously confirmed it would continue with the beat-'em-up series after the departure of eccentric creator Tomonobu Itagaki. The Team Ninja developers have been singing PS3's praises lately, too.
Eurogamer will be in San Francisco for GDC, so we'll bring you the news direct.
