There was apparently a podcast that divulged more information (I don't have a link at the moment)
- Alchemical items have "levels" from 1 to 20
- Bombs were supposed to require two hands to use, but that's being changed to one hand
Also from the comments, PF2 will NOT use item weight, but a "bulk" system similar to Star finder.
Another comment is that alchemists can get more resonance, which is rather important because they need it to use magical items AND wield alchemy.
The start of day items, as you guys have guessed, are subsidized for a better rate if you can predict ahead of time which items you will need and make duplicates. Plus, the alchemist gets a class feature that adds extra resonance and scales,
