According to numbers provided by Bethesda boss Todd Howard, the studio currently employs 180 people, and in fact, they’re not done with their expansion.
Bethesda are, however, currently working on a total of seven games, so it makes sense that they’re increasing the number of people working for them.
However, we also know that we won’t be hearing about a Skyrim sequel for a long while yet, but you never know.
Bethesda may do a Fallout 4 and announce it all of a sudden like they did during E3 2015.
