This might not be a hint, but we do have confirmation that the team isn't done yet with the game:

When asked about post-launch expansion plans for Baldur’s Gate 3, Larian Studio’s senior product manager, Tom Butler, said the team “want to do more” with the hit RPG, but what that looks like is still uncertain.

“We’ll carry on patching for a while and then we’re all going to take a holiday and then we’ll figure out what we do next,” Butler said in an interview with IGN. That holiday would be well-deserved after the game’s acclaimed launch and the three years of early access before that. “But at the moment,” Butler continued, “we genuinely have discussions. We want to do more. We don’t know what yet.”
