Predictions for a release in 2023 and a release in Q1 (January to March) 2024 have always been effectively the same thing in this thread, since both are derived from the assumption that a tapeout of the T239 SoC occurred around the middle of 2022. Initially, the predictions based on this assumption were for a release in 2022 or early 2023, since product releases using a new integrated circuit roughly tend to happen 6 to 12 months after its tapeout, but after that the predictions became based on the maximum possible time period after tapeout that still makes sense, the consensus of which seems to be around 18 months*, which coincides with Q1 2024.
This is all opposed to the predictions of a release in the second half of 2024 or later, which would likely mean that the assumptions about the tapeout of the SoC were wrong in some way.
* These timelines for an SoC tapeout to product release are based on the long history of semiconductor production records, the data of which I don't have immediately available. This post is just a surface-level summary of previous posts in this thread which have outlined all this in more detail.
