Actually, I think it does. Most of the serial numbers are actively collected on eBay, so it doesn't matter what the forum is called. Also, looking at the entire list, we have 60 recorded Nikon units vs 29 Fujifilm cameras. Obviously, we can't know for sure if the units sold on eBay (and those recorded on this site), are really representative of the number of units sold by each company, but I think it's a good indicator. And: It's the only real info we have - everything else is just speculation. A Nikon/Fujifilm ratio of 2:1 sounds plausible to me.
OK, there is no hint, that the Fujis are more than the Nikons. If ebay is scanned regularly, the numbers are a good indicator for the ratio. But if you take the numbers found on ebay, the E2Ns should be very rare - but i do not think, that it is.
