Call of Duty: Black Ops III Campaign Not on PS3/360

Activision and Treyarch announced this morning that the PS3 and 360 versions of Call of Duty: Black Ops III won't have the single player campaign that the Playstation 4, Xbox One and PC players will have on November 6th.

They believed they couldn't replicate the scope the campaign that is playable in 4-player co-op on the current gen versions for the PS3 and 360, developed by Beenox and Mercenary Technology. Multiplayer and zombies are gonna be all last gen players are getting for this year's game. To compensate for those players, a digital download of the first Black Ops will be included on PS3/360 versions of Black Ops III.
Those versions still gonna cost $50 and with such a pivotal feature gone compared to the current gen versions, is this a sign of things to come for last generation versions of blockbuster games and also the Call of Duty franchise? Can they possibly go only multiplayer next year? You can make arguments for campaign not being played much by fans these days, but I still believe it's a big deal to have in these shooters.
Let us know in the comments below what you think of this decision and whether or not it's a sign of the future for the series.
