The Playtest materials dropped on August 2nd, and I’ve been looking at them and working through how they would work and apply since then.
I have found a few typos, and the first errata was published to address the issues that I and other reviewers have found. This shows that Paizo is watching feedback and responding to the playtest community; which is very positive to see.
There have also been disclosure that the playtest version of the rules are not the full set of rules to be implemented, and as such there will continue to be revisions.
For now, we will keep our stated course of publishing for PF1.0 and 3.5E communities, and I will continue to await the final release in 2019 of the final rules. At that time I’ll see what the path forward shall be; but I’m optimistic as I’ve related above that Paizo will keep working on creating a welcome new rule set for another 10 years of gameplay.
