Except they allowed pre-orders to be grandfathered in...
You have to remember there are a lot of people who don't follow this stuff day to day and might not know about how the new plans will effect them. I am guessing there are alot of people who think their unlimited will continue to be grandfathered. There is a reason all of this plan info has come out in a somewhat confusing manner, this is all to plan. Also alot of folks don't like to buy something until they can see it or reviews are out. Trust me, Verizon will be getting a lot of people off the unlimited plans in the next couple of months which is just what they want.
