Dont consider this flaming But in my eyes, CoD is Nintendo in a nutshell. They are basically the same thing every year, but add little tweaks and little addition. I read somewhere that it isnt backward compatible due to the CPU. I think people need to focus more on the future games, and less on the past. If someone has a good number of PS3 games, they likely own a PS3. Just play it on the PS3. When i buy the PS4, i want them to be looking into the future, not worry about the games of the past.
