Still hoping for a Holiday 2025 launch (with a Switch Pro-like model launching with TOTK and maybe a price drop in 2024 as one last hurrah), but I also wouldn't be too surprised at a 2024 launch (preferably during the holidays). If we get no new Switch model this year then I would say that greatly increases the chance of a successor in 2024.
I highly doubt we get a successor this year though and I really hope we don't get a successor this year!
