Well...
As far as i know, marketing usually starts about 3-6 months prior release. So ... that would be next month?
On the other hand, Hoppa have good point, main reason for marketing is to let people know about your game, i hardly doubt there is even single person interested in BG-3 that never heard about it yet.
And if there is, i dont really know, what other marketing Larian would need to use, in order to let him know.
On the another other hand tho ... it dont really makes much sense to expect Larian to keep things completely quiet til August(?) ... there will be another hipe wave to start, im sure.
So ...
My gues is between end of May and start of June.
