Things I saw.
We have a domain list for the PHB: Knowledge, Life, Light, Nature, Tempest, Trickery, and War. I'd have liked a Death domain, but I guess that's for the DMG.
You can learn new languages and tools, but it takes 250! days to learn it.
Spare the Dying is now Stabilize from Pathfinder.
The magic section name-checked Eldrich Knight and Arcane Trickster. I guess we have a our Multi-class archetypes for mage/rogue and fighter/mage.
Fighter's using great weapon style re-roll a 1 or 2 on a damage roll. So no DoaM in Basic.
Variant Human is very nice.
You get more expertise as a rogue goes up in levels. Two at first, two at sixth. Makes multi-classing much less tempting.
Speaking of which; overchannel doesn't affect spells above 6th level and you need to meet BOTH class pre-reqs to multi-class. Wizards-going-nova-via-action-surge is pretty much a specific multi-class build, not a casual option. any mage will do.
They fixed the Uncanny Dodge/Evasion title swap from the playtest
We got five backgrounds: Folk Hero, Acolyte, Criminal, Solider, and Sage. We did not get Noble from the Pre-Gens, but we got the generic "scholarly" one.
That's what I saw so far from the PDF. I have a box set now to read.
