Yes, it's fat. And like I said it isn't as deep as other headtubes either.
Below are the head tube width dimensions from cyclenutnz:
Fuji Norcom Straight 48/43/53
Trek Speed Concept MKII 32/32/37.
Cervelo P3C 35
Cervelo P2C 35
Cervelo P5 45/38
Also probably worth noting is that, unlike the Cervelo models, the NS has the brake behind the fork crown. This requires a wider head tube at the base to 'blend' things into the down tube, but also eliminates the drag created by a front-facing brake.
