What about the MP? Would they release that seperately?
My post answered this, but I will clarify.
Activision is unlikely to release the full blown multiplayer component of the previous games
since that stands a good chance to affect sales of the current CoD release. Therefore I can see them releasing only the single player components of the Black Ops and Modern Warfare series in their own separate packages.
However, what I could see Activision doing to appease those is to release a mappack that collects the best maps from Black Ops and MW that would ONLY be playable on the new CoD that was getting released that year.
For example, lets say Activision released the Modern Warfare or Black Ops collection in September and come November when the Black Ops 3 came out those that purchased the collection would have access to exclusive maps (lets say 5-10) in Black Ops 3. Thoise maps would be a greatest hits collection if you will.
From a business standpoint this does two things: 1. it gives those who always buy the newest CoD an incentive to buy the older games AND it gives an incentive to gamers who may have stopped playing CoD an incentive to buy the newer titles.
Not exactly a pro-consumer thing, but from a business perspective I say it makes sense.
Not to mention there are plenty of petitions out there asking Activision to remaster Modern Warfare and MW2 for X1 and PS4. Activision is well aware that there is a groupd of dedicated gamers out there requesting them.
I can without hesitation say I would love a Black Ops collection.
