Apple's/ATT USA site alone crash while trying to handle over 600K preorders for the iphone 4 back on June 15th 2010.

Some people think that was world wide sales but that was just Apple's USA site for ATT which is a crazy amount and that amount probably would have been higher because probably 1/3 of people trying to pre order just gave up. I spent hours trying to preorder 3 iphones and only one order got through before I had to wake up to go to the store.
However, I predict Verizon won't even reach half the 600K preorder ATT set.
There are a couple of reasons and this isn't a "bash Verizon" thing. I am strictly giving my well thought out reason.
1. The main reason is that there simply aren't enough Verizon customers eligible for "full subsidy" $199/299 upgrades. ATT bent over backwards trying to "lock" people into 2 year contracts before their exclusivity ended. So ATT moved up plenty of people who normally would not have been eligible for the full subsidy upgrade (people were moved up to 6 months on their eligibility date). So more customers eligible, more sales. It's just simple math.
Verizon isn't bending over backwards trying to move up their customer's eligibility date like Apple. So Verizon won't capture the common upgraders who will want to wait until their full subsidy.
2. Number 2 is probably a more minor reason (except for diehards). But there are some people who anticipate a new iPhone coming sometime this summer and waiting a few 4-5 months is worth it to have the lastest/greatest. Verizon customers have waited at least the past 2 years so what's another 4-5 months for them. So this isn't a "new" iphone being released. Verizon is getting a phone that's been on the market for 7 months now.
So I am glad Verizon is finally getting the iPhone (I am a longtime ATT customer).
Hope everyone is happy finally (except Sprint/tmobile usa customers!).
But those are my reasons why Verizon will not match ATT's iphone 4 preorders.
