The MacBook Core 2 Duo (Merom) ships in the same surprisingly thin box as the original MacBook Pro (only 3.25") thick. Our machine arrived this morning (Oct 30th).

Note the lack of a pinhole for the iSight LED, as in the previous model. The LED is still in the same spot, and there is a circular pattern of micro-holes allowing light through. The holes weren't evenly drilled on our machine, letting more light through on the left side than the right. We didn't have a good enough lens to capture the effect.
