Odd.. I work for the Microsoft Partner Network, and our Cloud Essentials partners are already receiving all these plans in addition to the reworked plans for E1 through E3.
I find it interesting that the article says the new updates began to be shipped on the 29th. I've been processing Update kits for new Cloud offerings since the 21st and we've already got partners with these new plans and benefits.

I guess it doesn't really apply for End Users.
Oh well. Another reason to join the Partner Network
