Who knows? There are so many new things being tested right now. For the QBZ 191, they could always just go the way the admins have said previously where they just replace the entire upper with something more modern. Then there is the clean sheet design of the "as val" version of the QBZ 191, which could also have a replacement upper reciever to the regular 5.8. We've also seen what looks like a 6.8 variant of the QBZ 191 on a wall somewhere.
Other new stuff not related to the QBZ 191 is the bullpup anti-material rifle, the grenade launcher rifle, the new shotgun, etc. etc.
There does seem to be some large budget going into small arms development, so anything could go.
