Sounds like this will very much be in the vein of “5.5” plus adding some digital tools that look pretty cool, though I have very little confidence in Hasbro getting it right.
Here’s a direct link to the first batch of playtest material for anyone curious. My initial takeaways are that it allows mixed racial backgrounds easily and there’s a much greater emphasis on feats than 5e.
Great Weapon Fighting, Polearm Master, Two Weapon Fighting, Crossbow Expert. One or two of these feats is basically mandatory for every martial character in 5e, because they directly increase that character's damage.
The feat system naturally encourages everyone to take combat-related feats because it makes you choose between increasing your combat effectiveness or increasing your versatility out of combat - but combat is the place where your and your friends' characters are most likely to die so of course it makes the most sense to pick combat options whenever possible. This is one of the major design problems that was introduced in D&D 3 that was not fixed in D&D 5, though it was significantly reduced by reducing the number of feats so at least the players that need to pay the feat tax can move on to more interesting choices relatively quickly.
Pathfinder 2e fixes this problem by having multiple kinds of feats. There's skill feats (which are ONLY non-combat feats), general feats (which have some combat stuff but it's pretty minor), and class feats (which are almost all combat stuff). This gives breathing room to players to make choices that make their character more interesting, because the number of combat-related feats you can take is less than the total number of feats you get.
