I'm not expecting to see a brand new 2025 "23rd Edition" of The Chip Rack at the show next week, though I haven't seen promos either way from SSS Publishing. They may well have the 22nd Edition copy there for sale.

The most recent edition shown for sale online is 22nd Edition, from 2024. Here:

As Spragg (and all the SSS's) have been busy with the CPC sale, etc. I assumed the 23rd Edition won't be out until June 2026 (or perhaps post-2025 Convention in the next months).

Just my guess though. In past years, if there was a brand new one expected, they would have been marketing it by now.
