~Dedicated servers came back
~LAG was minimal
~Deathstreaks were thrown out the window
jeez, could you bother to search a bit??? this was confirmed by treyarch already, with dedis, you can asume that there is no lag, and i doubt there will be deathstreak in BO since they were gamebreaking or should i say control breaking in MW2.......
I don't know... Good thing this will never happen because nothing is perfect.
