For what ever little it's worth, it looks like I was right: http://www.pcmag.com/article2/0,2817,2380635,00.asp
I got shouted down here every time I brought this up.
They may be holding out for a new release rather than committing to a contract/service now.
A lot of us will change, but that demand is going to stay pent up until our upgrade cycles stick around. The pricing just isn't right ($600 without an upgrade), whereas coming from AT&T $200 isn't that bad. Verizon still has many eggs waiting to hatch in its customer base.
I don't think lack of early sales reflect the lack of value of the phone, just the fact that people know they can wait a bit longer and get it for 1/3 the price.
Plus: that "bit longer" (into summer) offers hope of it being an iphone5.
