I think they're going to air all the remaining episodes this month. Take a look at this episode list: https://looneytunes.fandom.com/wiki/New_Looney_Tunes_Episode_Guide_and_List
And once all of the episodes get aired, that'll be it for "New Looney Tunes". Because we're going back to the classics with the new series that's coming soon.
...which unfortunately will take a year for us to wait because they will be releasing in 2020 on a new WB-made Streaming Service. As I heard from Jerry Beck.
