We can only include SRD content in the system itself due to licensing, but Pelgrane is working with us now on releasing more content. Specifics are still being worked out, but things are in progress.
That’s my system! We’re really proud of the system/sheet we built for Foundry VTT, and we’ll definitely be adding support for the new edition once we know more about it. The new edition being backwards compatible is a great sign for that being possible.
