Call of Duty: World at War is 'next-gen only baby!'

Variables
a = Call of Duty: World at War for Xbox 360, PlayStation 3 & PC
b = Call of Duty: World at War for Wii
c = Call of Duty: World at War for PlayStation 2

Proof
If a=b, and variations of c have been known to equal corresponding variations of b, then does a=c?

... Yes? Well, the problem is c doesn't exist. Call of Duty: World at War will be "next-gen only baby!" Treyarch studio head Mark Lamia confirmed with Joystiq, correcting an earlier report that the game would mark a return of the series on PS2; the first since Treyarch's Call of Duty 3. Despite claims that World at War is "not a different game on Wii" (with, um, a few exceptions) -- and therefore, wouldn't be all that different of a game on PS2 -- Activision and Treyarch have apparently retired PS2 from duty ... for good.
