You mean Obsidian?
Well, not much of a chance for Fallout 4, since it's in Bethesda's hands now. But maybe another spinoff in the future?
Yes, Obsidian but I wanted to be more specific because not every development team in it is as skilled as the one that created F:NV IMO.
Yeah, FO4 will definitely be a Bethesda game and as such, I'm sure I won't enjoy it. Like Oblivion, FO3 and Skyrim it will be focusing on exploration only. Story, dialogue, quests, characters and combat will again be neglected.
As it is, nothing short of an Obsidian-developed Fallout game will please me.
