We recently revealed that Metro 2034 will be in 3D, and we said that the chances are that it will be only on PC and 360, but it looks like that might just change.
According to Dmitry Glukhovsky, even though Metro 2033 was only on the 360 and the PC, a PS3 version of Metro 2034 will happen.
Dimitry explained that they wanted to make 2033 on the PS3, but the problem was that it would take the company six months to port the game, and a solution to this problem was to move on to a sequel.
No release date has been given for Metro 2034.
