in the last series kira got freedom @ around ep 37-8 n this tym shinn got his destiny @ 36 so there's a lot of space 2 tie things up but since athrun n kira still hav nu suits making it seem lyk the series will go on longer. since shin is the main character the focal point wont b on kira/ athrun so n ending @ around ep 50 is reasonable even though their nu units r coming out
