It seems as though Hitman 2 is not the only game in the series coming to PS4 and Xbox, as both Hitman: Blood Money and Hitman: Absolution were both rated by PEGI, the European Game Classification Board. And, while it's not an official confirmation, the vast majority of games rated by PEGI end up being released.
We first played Hitman: Blood Money back in 2006, on PC, PS2, Xbox, and Xbox 360. Hitman: Absolution was released six years later, on PC, PS3, and Xbox 360. As for Hitman 2, it will be arriving on November 13.
