At this time, the Official Cert Guide for the 300-501 SPCOR exam has not been announced. However, I would recommend checking the Cisco Press "Coming Soon" page page periodically for updates on upcoming guides. A handful of new certification program publications are set to start rolling out in the Fall of 2019.
In additional, training courses for new the program exams will also continue to become available over time. Please consider taking at look at the CCNP Service Provider Certification and Training Program page and/or CCIE Service Provider Certification Program from time to time for any updates on the official training availability and/or resources under Study Materials. As you might already know, the new CCNP Service Provider and new CCIE Service Provider certifications share the same "Core" exam.
The exam blueprints are already published, so feel free to review the 300-501 SPCOR Exam Topics page to get familiar with the content/topics your expected to know for this new exam.
Best of luck to you!
