Is this the end of four cour Gundam series?

Possibly, but remember G-Reco only had two cours also and IBO that came after that had four course splits into two sections after that. IBO's second set of cours also was greenlite quite late in S1 to my understanding though I don't know whether that was ever confirmed.
