Does the newly released book "Core Java for the Really Impatient" covers all the portions of the previously released "Java SE8 for the Really Impatient: A Short Course on the Basics (Java Series)"

Yes, with one exception--Core Java for the Impatient has no coverage of Java FX. (There is an overview chapter in Java 8 for the Really Impatient.)
There is no reason to buy both books.
If you are already experienced in Java and just want to catch up with the latest, then the "really impatient" book gets you there quickly.
If you are not an experienced Java developer, and you want to become one, get Core Java for the Impatient.
