Not that I have a personal stake, as I don’t have either console, but has it been confirmed that BG3 won’t be coming to XBox? The only mention of exclusivity I can find mentioned in any news article so far is current generation exclusivity, ie not PS4. But perhaps more was said in the State of Play segment?
