Panasonic Japan published the CP+ presentation page:

The theme of the CP+2023 LUMIX booth is “NEXT PHASE WITH LUMIX“.

Whether professional or amateur, LUMIX will continue to evolve in order to contribute to all creators who want to challenge new expressions and fields.
Focusing on the Micro Four Thirds single-lens camera GH6, which enables a new time expression of 4K120p, and the full-size single-lens camera S5II, which supports even more aggressive shooting with on-image plane phase detection AF and powerful image stabilization. In addition to touch & try unique to the venue and a photo walk where you can experience the actual machine, we have theme-based seminars by up-and-coming creators and equipment-based seminars that delve into the appeal of products. We will continue to develop content that will be useful and hints for creative activities.
From those who want to open up new ways of expression to those who are having trouble choosing a camera, please visit the LUMIX booth!

There is yet no hint about possible new camera/lens announcements…

Red35:

It is Lens OSCAR time, to reflect and rate all the M43 lenses that I reviewed in 2022 and name the BEST for my first ever RED35 Lens Award 2023. I nominated five from many many that I tested and each of the nomination is great for any M43 photographer and videographer. Watch and find out which one came out on top and beat the others and claims the BEST LENS 2023 award.
