Originally, Philips (or Signify, as the company is actually called) was supposed to update its bridge with support for Matter sometime during the first quarter of 2023, but that will not happen.
This is what Philips tells Hueblog:
For the launch of Matter, we are working together with many partners in the smart home industry. With Philips Hue, we always focus on convincing quality to meet our customers’ expectations. Therefore, we will take a little more time than originally planned for the Philips Hue Bridge software update before making it available to all consumers. We will inform you as soon as we have a concrete date for the release of the Matter software update.

There is currently no information on when the update will be released, but once it does, all existing Hue lamps and accessories except for the Hue Play Sync Box and Tap Dial Switch will work with Matter. So far, the Matter update does not mean that users will get any new features, but it should at least be a little faster to turn on and off the lights depending on which app is used.
