Wing Commander CIC

Im relatively new to the WC universe and I was wondering about its future. Beyond some cool looking MODs, a GBA Prophecy, and fan fictions it doesnt seem like much of anything new is coming out. Why is that? Wasnt Prophecy successful? And if so why is origin not continuing with the Nephilim war. I wanted to play some more with the characters and the ships from the game and Secret Ops.
