In fact - and even more so after the CS-5000T was unveiled, I slowly get the feeling, there is no GJ-11 ready ...
We've seen the demonstrator in 2013 and since then NOTHING but mock-ups. Itt's almost like Nessi, the Yeti or the WP-14 Kunlun.
I don't think that they would consistently show it at these sort of official appearances -- this one being as official as the come -- if it truly wasn't in hands of the PLA in a relatively advanced form. It just isn't the PLA style.
What this pattern shows to me, is more that the PLA is very much capable of keeping things hidden from us if they want to, IMO.
