I think his story along with the early pilots would have been interesting and has unlimited potential. From the early Kaijus & Jaegers, getting cancer from nuclear exposure and more.
Good move by keeping it away from a summer release. Especially in 2017.
Hope we see Gipsy as a Mark V now and maybe Cherno Alpha back and badder than ever. I hope they don't do Kaiju/Jaeger hybrids. No need to fix something that isn't broken.
