At the E3 event just now, Tim Schafer announced his studio would be joining Xbox Game Studios.
After making the announcement, Schafer showed off a new Psychonauts 2 teaser. Psychonauts 2 was crowdfunded on Fig in 2016. Presumably, this new business development will not affect which platforms to expect the platformer sequel to appear on.
