I think its more tricky wording from them.
Customers will be contacted after 7 days, not that the shipping will start.
Could there possibly be some delays in contacting customers? delay by offering another deal or incentives
Some delays counting the 400?
Then they say items will be shipped as soon as possible?
Well dag if time is needed to contact customers, wait for replies and then count the 400, then prepare units (preparation is X factor also), then ship.
Its another dragged out delay tactic, all well planned.
Shipments could be April, May, June.
In the end I think they are grateful that they have somewhere to unload the older equipment, as they upgrade the datacenters to the Neptunes.
