WhyD70?

Something on Thom Hogan's site http://www.bythom.com revived a curious thought. Why D70? What made Nikon pick that number....it never really fit with the scheme in a numerical sense. I was snooping about the US trademark / patent website and found some interesting things. D200 is already a registered trademark...as were d60, 80, and 90. 50 and 70 are now Nikons.....300 is available. Wonder if the d300 will replace the d100.
Is this a pointless rant or WHAT!!!!
