Makes sense doesn't it?

The two year dev cycle which acti has been doing has gone well for now for them.

Key IW members left, and as a result, arguably the worst cod game, cod ghosts was released to little fanfare.

Sold well, but seemingly not as well as previous entries.

I think IW are working on a new ip for activision, probably still a first person shooter, and treyarch and sledgehammer will now be in charge of the alternating cod games.

On top of that, two key members of ND left recently for infinity ward. Now would someone really downgrade from the big bad wolf (ND) to little red riding hood (IW) unless they were excited about something, likely a new direction/new story.

And one of them is a lead narrative person. it makes sense, doesnt it. IW reputation with cod has been reduced, they arent the same company they were with the two dudes who left to make titanfall. And activision know that

I don´t think so.

Activision outright said that due to quality issues (and Ghosts disappointing sales) the 3 CoD studios (Infinityward, Sledgehammer and Treyarch) will each get 3 years to make  CoD from now on.

And people leaving from Naughty Dog to IW is pretty meaningless, because they got a better/ more important job over there (in the hierarchy).

adding to the replies above that Activision do already have a new FPS called Destiny (which is scheduled to be a trilogy) so I doubt the will add a third to the mix.

I doubt it. They're probably trying to make COD better.

I think between CoD and Destiny Activision have got things covered - traditional MP-focused FPS on the one hand, online, more open-world game on the other. I guess it's feasible that Destiny's likely success might encourage them to take more risks on new IP, but to be honest I think they'll just make more Destinys, probably not annually, but every 3 years or so

Plus CoD as it is right now consumes a huge amount of dev resources, with 3 full teams plus all the smaller studios they have making map packs and stuff, so I don't know if they have the capability without further expansion (though of course they definitely have the money to make that happen)
