I'll be shocked if BG3 releases in the first half of 2023. Larian releases patches every ~4 months on average (5 in this one's case), and the game still requires 2 more classes (monk, paladin), other companion maybe, alleged reaction system overhaul, and an inevitable variety of other small-to-medium adjustments. Plus, most games are delayed from their initial release date these days. I'd say we're looking at 2-3 more patches after this one before release, and 2 patches already takes us into the latter half of 2023.
Patch 8: Now Patch 9: November, 2022 Patch 10: March-April, 2023 Patch 11: ~August 2023 (optimistically the game will release here) Only slightly pessimistic Release: Fall/Winter 2023 Very pessimistic Release: Early 2024
