Larian are interested in active communication after 2 years of basically silence? Personally I would find an AMA session would be a bit of a damp squib because at this stage I think it's safe to say some of the most requested changes are not likely to be implemented. I guess it could be of use to people who want to ask questions about things that are already in game though.

I'd be surprised if there was any kind of event planned; the game Is still being made, why celebrate 2 years of development? Seems a rather strange event to mark. It's a bit like celebrating a year of making a film when it isn't finished yet.
