Watch adventure time follow?

Does anyone know where to watch season 4 7 8 9 and 10 of adventure time? On netflix there are seasons 1 2 3 and recently also 5 and 6. I would also like to see the 4th. And do you think that the seasons 7 8 9 10 will be coming to Netflix soon? Because the 5 and 6 have just come after a long time.

Cartoon Network Deutschland currently has the rights to the other seasons. You can also see them there.
