Metal Gear Solid composer Norihiko Hibino's website has revealed a new Konami title for the Xbox 360.
The site lists the game under 2009 projects, and has it as a Japan release only so far:
Bayonetta is listed as a PS3 only title on the site, when it clearly isn't, so an Xbox exclusive is just speculation at this point. Hopefully some light will be shed on this in June.
We can't say it enough - come on E3.
