Both Todd Howard and Pete Hines are essentially in "tease" mode right now. That's usually the marketing precursor for something new coming up in the not to distant future. The reveal that they have two games in "overlapping" production is not surprising, because they have expanded BGS quite a bit since Fallout 4 was released. But yes, releasing a new BGS game, say, every two years would make a lot of gamers, including me, very happy. Here's hoping product quality doesn't suffer from it.
