Back when Mojang was first acquired, it was mentioned that over half the staff there was working on games that weren't Minecraft.
However, in an interview today with someone who was leaving the studio, they said this:

The implication there seems to be that they're not doing anything that's not Minecraft?
When did they ever say they were going to continue with those projects? In their deal announcement they said:
Whats happening to the other Mojang projects, like Scrolls?
We dont know yet. Well share any news as soon as we do.
That info about half the employees being non-minecraft seems to come from a later book by a former employee and the context was that Microsoft referred to the company as 'Minecraft' -- making it clear they were not interested in the projects those other employees were working on
