It appears that Planner "basic" plans are just the same as before, and Planner "premium" plans are essentially "Project4Web" plans, with the same limitation that P4W tasks don't yet show up in My Tasks/Assigned to Me view.
Note that "Ability to see premium plan tasks in My Tasks (limited availability in preview at this moment)" is within the "Coming Soon" section of the post, so it looks like this feature hasn't launched yet.
I agree that it's critically important.
