All 3 dramas will start on the CW network in America in October when the new TV season gets underway there. It's basically a given that M-Net will or perhaps has already acquired all of them, depending on how they perform and if they make it, they should be, could be on the M-Net channel (DStv 101) or M-Net Series (DStv 110) eventually.
All 3 shows enjoy high buzz - Arrow the most of all - all 3 look excellent judging by their trailers and what is known so far regarding premise and plot. Let's hope South African TV viewers don't have to wait too long before getting to see them.
