When will the new season start?

It was long time before this season and the last season. I watched the first episode of this new season and thought it was real good. I have actually cut down my tv watching by more than half and had considered not starting this show again but glad I saw it. Not really sure if that was a good move on my part due to the fact we may have to get rid of HBO due to our financial situation right now. Thank you for the response!
