I'ld say so for a couple reasons, possibly because:
-There is a discount for using dedicated servers since Microsoft is pushing the "cloud" for the Xbox One. Incentive.
-If they don't have dedicated servers for Ghosts on the 360, there will be constant host migrations like BO2 over the past year, and then the Xbox One version won't have any. Avoid embarrassment.
Why didn't they have dedicated servers sooner than now?
Expense and lack of competition
I don't mean competition as being dethroned in sales and the highest selling game. Just competition as far as another game creating higher quality formula for connectivity in multiplayer. Since Microsoft will be having all these servers available, CoD will now need to adjust, to make sure they lead the way.
Some of my thoughts might seem negative towards the developers or Activision, but actually theres nothing more I'ld like to see than the future of CoD be successful and the community have a higher percentage of enjoyment and less frustration.
So its old news with a new vid. I knew this was an older topic but did a poor job with the search function finding your thread, my bad.
I just wonder how long I played before I actually noticed I wasn't seeing host migrations. I became content and less frustrated that I wasn't being chose as host. And that happened around the same time Treyarch released the May 23rd update details about "improving and expanding who can be host of the game lobby".
