One thing, i’ve particularly been keeping my eye out for is whether or not we will have campaign scoring/medals thrown in. For me that’s been one of the greatest things about all the campaigns since Halo 3 and have increased replay value for me. Does anyone know whether or not this has been confirmed or addressed as yet?
The other thing is time. Given that a lot of achievements are confirmed to be time based, I would be hoping that at the same time there will be the inclusion of a timer as well (as is the case when scoring is enabled in the other games).
