After the Adam Smith interview, I actually think the best title is "Baldur's Gate: Absolution" after the Cult of the Absolute that has arrived in Baldur's Gate.
I’m still perplexed why it matters so much, not that I dislike your suggestion were Larian operating with just a working title... but it IS going to be BG3. People reallllllly need to get over this. Sorry buddy.
