Intel said that Nehalem is scalable and modular and in one of the slides it revealed something called iGraphics.
This is definitely proof to our story that Nehalem will have some kind of a graphics core inside, but we are not sure if this is the case with all or just with some of the CPUs. This decision probably comes as the Northbridge becomes less relevant, as the memory controller is now in the CPU and the only thing you really need the Northbridge for are the PCIe lanes.
If you don't trust us, look at the picutre in Intel's slide.
