Eh, that has wishful thinking written all over it. They're not going to roll out their gameplay trailers and advertisements four months prior to release, are they?
It actually has 2 question written all over it.
But I'll answer your question to my question.
I dont know, iv not seen any gameplay trailers
there is a full year of 2020 its possible it's the last quarter.
Unless Larian have been working a lot longer on bg3 then we/I thought.
I Did not expect a release for at least 2 years
