These presets are now available in After Effects 2023. No need to download the beta version to see them. This project file is still useful as a guide to which presets are new, though!
This is an AE project file for the v23.0.0 beta version. It contains comps with all 50 new presets for graphic elements and text animations. I didn't create all of these presets, but they're not easily identifiable as "new" in the effects and presets panel, so I put each preset in its own comp for easier browsing.
