No it won't be coming to the PS3, but that's not a knock on the PS3 performance capabilities, more that it'd be financial suicide.
You have to think about development costs, PS3 porting is harder than 360 porting, Crytek would do better with selling rights to companies to use the cryengine (i think that's its name) then to waste funds porting a game that wasn't financially successful on the PC. They aren't epic here, who have had huge success with Gears and the Unreal 3 engine that the unsuccessful UT3 can be ported onto the 360 without to much worry about the financial situation.
if it were possible, they are better off porting to the 360 for the larger install base, though I would say that there are more PS3's in the world then there are high end gaming PC's in the general public
