Update 7 is the World Update US, which has already been released.
Asobo is now slowing down the release since they don’t have to rush bug fix as much, so from now we will have monthly updates (instead of bi-weekly) that alternate between Sim Update and World Update (so something like Sim Update 2, World Update 3, Sim Update 3, etc.) Sim Update are bigger than the ones we are getting for a while now and would likely contains new features (next one is VR). World Updates are the ones we got with Japan and US, so you already know what to expect.
