It was mentioned in the VA255 broadcast that Syracuse 4B is being launched in 2023.
The Syracuse 4 constellation will be progressively completed with the arrival of Syracuse 4B by 2023, and Syracuse 4C responding to the Armed Forces' need for connectivity.
Syracuse IV is a geostationary defense communications system for the French Ministry of the Armed Forces. The system comprises two satellites, Syracuse 4A, launched today, and Syracuse 4B, slated for launch in 2022.

However, Eutelsat has not confirmed launch vehicles for any of the three satellites.

There's more payloads listed for Ariane 5 then slots available. The upper slots have been mostly determined while there's more unknows with the lower slots. GSAT 24, Ovzon 3, MTG-I 1, Syracuse 4B, and Heinrich Hertz are all listed for Ariane 5 while there's only 4 more GTO launches left. Will Ovzon 3 launch with one of these payloads or has something been moved to a different rocket? Is the Ariane 5 with 2 light payloads your referring to the mission with two Galaxy spacecraft?
Arianespace will launch the Galaxy 35 and Galaxy 36 satellites together as a stacked pair in 2022
Multiple ESA mission webpages had their launch dates updated on November 8.JUICE delayed to NET August 2023:https://sci.esa.int/web/juiceQuotePlanned for launch in 2023, it will spend at least three years making detailed observations of the giant gaseous planet Jupiter and three of its largest moons, Ganymede, Callisto and Europa.https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=JUICEQuoteJUICE is scheduled to be launched in a window running from 26 August to 15 September 2022 on an Ariane 5 from the European Spaceport in Kourou, French Guiana. (A backup launch date is scheduled for August 2023, arriving at Jupiter in August 2031.)

Is it still planned to launch on Ariane 5 or did this delay cause a move to Ariane 6?[Re: Yiosie's original post in the Ariane launch schedule thread--JUICE launch delayed NET August 2023. That post was cross-posted here and to the JUICE program thread in the space science sub-forum.]

There is not much time.

It uses derivatives of the Vega-C first stage for boosters. That Vega-C first stage in itself is an evolution of the current Vega first stage.The Vulcain 2.1 main engine is a minor evolution of the Vulcain 2.0 engine which is currently in use on Ariane 5. Changes mostly concern simplifying the nozzle and slightly increasing the ISP. The payload fairings are slightly modified versions of the ones flying on Ariane 5. The core stage propellant tanks and plumbing are direct evolutions of the same items on Ariane 5. Only the Vinci-driven upper stage is "new", but the core of that upper stage carries many design elements of the current Ariane 5 ECA upper stage. And Vinci is by now the most tested upper stage engine in the world, courtesy of it having been in development for the better part of 20 years.If anything, the Ariane 6 is an evolution of Ariane 5. That was not the case in the latter half of the 1990s. Ariane 5 was a radical break from the previous 4 Ariane models.As such the risks involved in the first Ariane 6 missions are very much less than the risks involved with the first Ariane 5 missions.Ariane 6 is not like the all-new Ariane 1 or the all-new Ariane 5.
