I guess we will not know if either assertion is true until the consoles launch.  You are guessing the same as I would be.  You have no idea if CoD will work on the PS4 without an update.

Except, we do know that CoD will play without an update.... so...

How do we know that, do you already have a PS4 and Cod?
