My thoughts exactly.... Possibility to merge with CoD is my top priority and as it is confirmed now: I'm happy now.
As I will buy BoM anyway I get the improvements for CoD as well and I can wait for the new effects till the sequel is goint to be released.
All in all we will get our new overarching series
Only the statement about the coops worries me a bit. the release of a proper coop mode is a MUST!
