Hi Jesper,
Yes, JMP 19 will restore SAS Integration. There will be a few changes necessary to get JSL programs to connect. I believe JMP 19 will actually improve on SAS Integration, as SAS Viya access will be supported and you'll be able to use CAS tables in the SAS Query Builder. If you have access to the JMP Early Adopter program, you can try these features out now.
