In open shift 4, there is no need for system admin. Open shift operators manage everything. It's a paradigm shift. OS is upgraded when an app needs upgrade. Somewhat similar to Android.
Subscription manager is gone. It's changing to online subscription management. Red hat will allow to oversubscribe but will show warning if there is a license breach
Every single component in open shift 4 is operator enabled.
2 years of full support for every open shift 4 release and 5 months support for critical security bugs and updates.
With RHEL8, Red Hat will be creating Universal Base images for ISV partners. All containers provided by Red Hat will be based on this UBI image.
Application Migration Management is being launched with Open shift 4.2. It's upstream is Velero. It is migration tooling. Migration tooling can upgrade from openshift 3.6 to 4.
Hosted open shift is in most demand.
Red Hat has created 2 week (10 days) Openshift bootcamps to impart the knowledge of openshift
Upgrade to Rhel8: Rhel7.6 can be in place upgraded to Rhel8 with one single command : leapp - - debug upgrade

Red Hat Learning Subscription (RHLS) is being offered at a discount with RHEL. Until early next year. Tell all your Red Hat customers about it so that they can benefit from the discount.
Containers Vs Apps is like Cattle Vs Pets
Red hat does not certify partners for openshift. Rather Red hat certifies images and now also operator images
Never cut paste code from stackoverflow. They are not opensource.
