Will forum section change? will there be section like 2 way communication player-dev/moderator/someone who can give answer about in game questions ?

Yes there will be new sections, but there won't be any 'player-dev' communication, the devs are far too busy to get onto the forums to answer questions. I don't know what the exact sections will be that they'll add, but it will be the same as it is now where answers and replies will come from the community which includes regular members like you and me and also moderators.

Get ready for the influx of newbies as well. Got to be gentle with them as most arent use to what is a pretty peaceful forum. Mods will be in for their biggest test yet I reckon, and with the support of the current community I reckon we will all live through this.

I won't be posting because I will be playing the game.

I on the other hand will be mostly playing and occasionally cussing under my breath while having fun

player dev communication will never happen a large part of fan base wants to have their children and another part whats too have place of work nuked so yeah never gonna happen.

I'm sure there will be people who would criticise FO4 for being shallow and dumbed down.

I assume the forum will be heading over to Bethesda.net at some point...
