This is Activision.
The company that has milked the CoD franchise on a yearly cadence and made Billions for over half a decade...
They can afford to build a seperate version of the game for last generation on a different game engine, you don't need to hold back the development or "dumb it down" for the Xbox One/Playstation 4/PC version so it functions on lesser hardware or strip away features.

It's all about net profit. Campaign won't add much to the experience on last gen, so no need to delay the entire game for it. Just remove it and charge a cheaper fee. Same reason why they don't port to wii u. They could if they wanted to, it's just not worth it
