CIG switched to Amazon's Lumberyard fork of CryEngine, which I suspect will become the canonical upstream, provided Amazon keeps up it's support and doesn't alienate people with crazy Amazon service tie-ins. My (not very in-depth or researched) impression is that the original team at CryTek suffered a brain drain long before this latest round of financial difficulties (e.g. lead engineer Tiago Sousa moving to id Software to succeed John Carmack as lead renderer guy), so I suspect they don't have a huge the "real change is happening in this branch" advantage over Lumberyard anymore, and Amazon is surely more stable than CryTek is.
