"First week activity of BO2 will be more than double that of Halo 4's first week activity on XBL"
May I quote you on that if and when we get access to those numbers?
As for Halo losing popularity each year, I don't see it, Halo 4 is carrying way more hype, pre-orders and coverage than Reach did.
Also:
Halo -> Battlefield on 360, that's just fact so it's a odd thing to say mate.
