Nikon AF speed?

I was wondering if anyone knew what is responsible for AF speed with Nikon DSLR's. I have a D70 and at the end of the month I'll be upgrading to a D80. I'm hoping to get faster AF, hoping I pick up some speed. I've heard with Nikon that AF speed is determined by the body, but Canon it's the lens. Does this sound right?
