Historically Larian has always been tight lipped about launch specific dates until they could set them in stone. My gut reaction is they are still fine tuning and we will hear actual date info in the next few weeks if they can hit their deadline.
I know XBOX gamers are anxious to get their hands on the game but let them have time to make sure they have it right

Larian is very silent about everything not just xbox. I value higly this company, but their presence on this forum and all other forums is atrocious. I have zero idea what do their community managers do for living, but it is not interacting with community as whole (= make information available when it develops).
There are certain promises about fsr and technical things which have been mentioned since maybe once in one sentece ”unexpected difficulties”.
Some other parts of life this kind of communication would make me change ”service provider”.
